Click the grid with the times/dates you are free for your meeting or event, optionally choose an event name and press 'CREATE EVENT' ... you get a results code and a link to circulate to your invitees. They see your proposed times and can click When is Good for them. Click 'view results' and enter your code to see all the feedback and the times that everyone can make.

If you request alerts the system will send you an email whenever there is a response.

Just click 'SHOW OPTIONS' and select the range of times you want to work with.

These allow you to change how much detail you - and your respondents - can use when painting availability. The number choices correspond to quarter-hour, half-hour and full hour chunks. The last button switches to a calendar view, which is good for planning full day and social events.

Below the results link on the 'event created' page there's a link that allows you to edit your event. If you don't have an account you may want to bookmark this page for access later.

Be careful when editing events that already have responses - as the warning says, theses will be deleted as a consequence.

The gray areas show the proposed times/dates for this event. Click on all that are good for you. Then type in your name and press 'SEND RESPONSE'. The person who set up the event will be able to compare everyone's availability and will let you all know When is Good.

Click on the event link again and re-do your feedback - if you use the same name as before the system will check with you first, and then override your previous response.

If the event is linked to an account, login and click on the link in the 'your account' page. Otherwise, click 'view results' and enter your results code.

You will see everyone's responses and feedback. Times/dates in green are good for everyone. Any 'near miss' times have a small red dots to show how many people can't make it - mouseover to see the problem names in red.

If you mouseover each of your respondents, you get their individual availability. You can click on any name to temporarily exclude them from the analysis. The names are ordered from most flexible to least flexible.

Click on a time/date in the grid to get a popup with a full report of who can/can't make it and a an iCal link to add the chosen time to your calendar or send out as an attachment.

Shift-click on a name.

If you don't have an account, didn't request email alerts and have lost the results code, you may still be able to track down the 'event created' page through your browser history. The page will be called something like When is Good : Event Links.

Not if you don't want to. The system works just fine without an account.

With an account, you don't have to worry about losing the results links. You get a simple 'dashboard' listing all the events you have created, which you can then edit or delete.

The system is also slightly more secure for events attached to accounts - you need to login to see the results. Without an account, any one who knows your results code can access the page. This might include anyone who has access to your browser's history.

Because of a small design problem (that we're working to fix) there is one slight disadvantage to working within an account - if you need to share your results with other people, you would have to give them your password and consequently full access to your account. Sorry about this. We hope to have this fixed in a release in the near future. (Thanks very much to all those who gave feedback on this point).

Any event that used your account email address for alerts can automatically be imported when you first login.

To link other events, just go to the 'event created' page and request alerts to the same address.

This is the link that you will be circulating to the people you want to attend your event. By default the system suggests a short unique (i.e. hard to guess) string, which will work fine. But you are welcome to specify something else.

The main reason you might want to do this would be if you were organising lots of different events and wanted to make it simple to track which link was for which event.

We're planning to add an optional password for events links in the near future.

However the system can be used completely anonymously - just stick with the random URL, and keep the name fields and comments free of personal data (e.g. ask your respondents just to use initials when completing the form).

Also, please see our privacy statement.

If you are sure everyone is in the same part of the world, you can safely ignore this option. Otherwise, simply click 'Use Timezones' and your browser will auto-detect your local time. The times you then select will be automatically adjusted correctly to everyone's own timezones when they view your link.

Here's an example: you are in New York and suggest a conference call any time tomorrow afternoon. Your invitees on the West Coast will see this proposal as the morning, while the ones in Europe are working with times in the evening. Everyone clicks the hours they are free and you see from the results that 11am is perfect. You click on that on the results page and get some text to email everyone showing what that translates for each invitee.

The only potential issue is if the auto-detection doesn't put you in the correct zone. This might happen if you are travelling with your laptop. Just adjust the dropdown until it shows the correct local time and carry on as before.

Full support for languages is still being prepared. Check back for progress on this one. (If you need a language that isn't yet supported there will be a chance to contribute a set of translations.)

We've added an iCal link on the results popup (just click your chosen time/date on the results grid). This should open automatically in your calendar program, or at least be something you can 'import' into it. You can also attach the iCal file to an email to circulate to the participants.

This feature is new and we're keen to hear any feedback you have about it.

Future additions may include the ability to upload your own iCal at the point you create your event - this would limit the suggested times to those you were free.

Just email us at contactus@whenisgood.net and we'll get back to you. The service is quite new so we're particularly interested in any problems / feature requests.
