As for the slogan. I'm cool with just the "It's a fanfic thing." (I do want to nitpick because I'm an editor and it's niggling at me... the fanfic shouldn't be capitalized.

I know this isn't the final mockup, though, and I'm open to hearing other opinions if people want it capitalized. :))
I capitalised the Fanfic to kind of inflate the importance of the word, to indicate some bigger, global thing, to turn it into a 'name' of a phenomenon. Grr, I can't really explain the idea I was getting at.
Anyway. I'll deal with that on the next round ... or maybe more people could comment about this.
