It should be possible to cancel rendezyous (e.g. if there is no good suggestion among the ones proposed), or simply to delete test rendezyous.

People sometimes lose their links or the mail is being trashed to the Spam-Folder

Should the Rendezyou client support adding new suggested events, either by popping up a dialog box or by having the user fill out the event information in the suggestions "list"?

This would be slicker than deleting an event - if that were possible, and making a new one. Just deleting a finalized event is more important than this one.

Right now you can only one date as a final one. What if you want to agree on two or three dates for meetings?

Anybody want a German version? – Vote this up.

Users should be able to sign up and log in using their OpenID accounts.

It would be nice to prepare rendezyous while in the park or on the plane. They would get saved and the invitiations would be sent as soon as I go online.

Maybe a popup menu item "Add to Rendezyou" when right-clicking on an event? Or a new item in the iCal menu? Or at least a service in the global Services menu?

This would add the selected event to the current rendezyou (or start a new one, if the Rendezyou client app isn't open yet).

My mum said she wants a weather forecast for each suggestion to simplify the decision-making process.
