I'm on CF.Net, Lampstand Forums, Apple Forums, iPad Forums and iPhone Forums. Lampstand Forums are kind of dead, very low traffic, and I'm going to remove that forum from my Tapatalk. I'm not sure how the Android version of Tapatalk is laid out, but there should be a Search or "Add forums" option. There you can enter a term such as "Android" and it will return a list of forums for that category. I'll bet you can find dozens of Android forums that support the Tapatalk plugin.
