I'm looking for an online webapp to manage event planning.
Here's the list of ideal requirements I'm looking for:
- To be able to propagate invitations to friends through either email and/or social network(s)
- Can export a specific event entry in vCalendar format
- Exposes an external API to retrieve a feed of events for a specific user/group
- Displays a link to an RSS/Atom feed of events for a specific user/group
- Displays a list of people who are invited and their status (attending/maybe/not)
- Has a description field for the event
- Has attached comments
- Includes a rating for specific events
- Includes a photo/video gallery or a way to link to an external gallery (Flickr/Youtube).
- OpenID login
Note: To preserve cleanliness please only put one option per answer.
