Automotive (1 club), Books & Literature, Celebrities (1 miscategorised club), Characters, Comics & Animation, Couples & Shipping, Fanpop Users (my own club which I got automatically added to), Movies, Society & Lifestyle (1 club), Television, Versus & Mashups.

If you go to the "my clubs" mosaic on your profile and click "list", your clubs are grouped by channel and easy to count. (Thought I was gonna have to do some Serious Research for a minute. Wake up, brain! XD)

^That's how I checked too. It was more work finding out the total number of club channels.

Thanks for commenting with an explanation of how to check - I didn't think of doing that.

Wish I could've saved you some hunting: they're all listed on the homepage, bottom right. I am a fountain of (useless fanpop) knowledge. XD

^That's where I looked (eventually). It was still more work because there were more to count :P
