The Orzhov welcome you. Please leave your belongings with the Obzedat. They are not yours anymore.
Hi, I'm a european crested tit, and a very small punk rocker!
Hi and welcome.
Files are uploaded in the Files section of a game, not in the forums. I don't know about fan expansion. You can upload them on another wesbite (such as google docs or dropbox) then create a thread in the Variants subforum on the game's Geekpage and post the link there.
