I have a decent hand at graphic art. Just depends on what you need.
Something to represent each of the houses, and something for the Adults - for now. Perhaps split the Adults into Three Categories - Order, Death Eater, and Neutral?
When I get around to making the OOC threads, I was going to dig around to see about getting graphics to use as headers in those threads. The Rules, the Character Creation thread, Then a Header for each of the GM run 'main' plot threads. As well as the OOC thread.
ALso, I'd like to find out how many of the players are still paying attention? I want to get a head count, and find out who all will be around for the Rp.
