For a website with CB i'm looking for a planning tool to plan meetings.
If it's possible, it should be an application that can add events (by a registered user) which several people (without registration!!!) can give their availability / rate / comment / whatever.
For example: i want to organize a evening with friends. As a user i add a calender and add several date's. My friends get a link to this calender and can give their opinion on the given date's.
In dutch, there's something like: datumprikker.nl.
At least, it has to be where several people can react on date's. I know that there are several "reservation systems", but they view the availibility for one object (like a house), related to one person or user. I'm looking for a system that can link an object (like "meeting" or party) to several persons.
When there's at least nothing thats working together with CB, a standalone application is good to (through wrapper).
