I have the forum set up for the RPG. (A toughie. Took about 5 minutes.) It has a chat room attached. So the two of you need to send me your emails (either post them here or send them to hogwartspost@yahoo.com) so I can give you the login and password.
I'm assuming you can figure out how to add stuff to the top of the forum, link pages, etc. If not, I'll gladly do it for you, of course.
