The "All About" threads are Ultimate Central's version of catch-all threads for major topics. They are a way to discuss aspects of certain categories that may not be able to sustain their own threads. The All About threads are rebooted after every thousand posts (give or take), and are numbered and subtitled.

There are a couple unofficial "All About" threads, which serve the same purpose but don't start with those words. These include The All Sports Thread, and a Music thread.

All About Comics
All About Food
All About Movies
