If you don't know about 20in20's, you sign up with your chosen character (or pair of characters in this case), you get 20 'themes' which you use to make 20 icons in 20 days. You post 'em, people vote on 'em, and the LJ world gets a whole load of excellent new icons!
I'm signed up for Dean Winchester this round and am *really* looking forward to it - but they need more members before they can start. So, wanna celebrate your favourite BAMF? Go join and sign up!
