How does it work?
We've tried to make dayfindr as simple as possible to use.
You create your event first, specifying the days that everyone can choose from.
Once you have created your event, you will receive an email that contains the web link that you can use to edit your event (e.g. add more days, remove days, edit the description etc.). This email also contains a piece that you can forward to everyone that you want to invite.
Everyone whom you have invited may then update the days that they can attend, and you will receive an email every time someone updates their availability!
