WhatsThePlan.com - Plan Events Online
WhatsThePlan allows you to plan events, post them for everyone to see, and save them for later. Generally event planning sites don't keep old events in view, but with this site they're accessible so that the people who attended the event can post pictures, comment on the event, and check out the people they might have seen there. You can export your events to your own calendar, or upload them to the site. You can also subscribe to specific users' events and share what's going on using Facebook. So check out what's happening near you and who's planning on being there. read more here.
