According to TechCrunch , Fatdoor has closed its doors and will reopen as Center’d. From the about page (via TechCrunch) —

At Center’d, we’ve been thinking about how to solve the challenges that exist in making plans. From the smallest get together, where you just can’t decide on where to eat . . . to the large fundraisers and school activities that require signups and hundreds of emails and weeks of meticulous planning . . ..

Hear us out. We can give you the tools you need to easily organize people, places, and times. Using the latest space-age technology, we have concocted features such as:

• Polling tools: Enable your guests to take some of the burden of coming to consensus on the place and time to meet.
• Task Management and Volunteer Sign-up: Now you can easily get the team you need to do the stuff you need.
• Connection management and calendar sharing: Now that you are suddenly so organized, and ready to pull off the perfect girls’ night out/summer camp/grandparents day/birthday party/first date/last date, let’s make sure those who are important to you can view your calendars. But not everyone, and not every event. We can keep a secret.
• Explore neighborhoods: We’ll even help you out with finding other places and events. How would you like a view of your world filtered by the recommendations of people you trust? How would you like to be at the center, and have the people, places, and plans you care about revolve around you, just waiting to be experienced? We like that idea. In fact, we like it so much, we built it.
