I know that there is a group on Last.fm for Chaosforge with a few people in it, so why hasn't DoomRL gotten into Facebook yet? It's basically free advertising. I have personally put up links to the DoomRL download page on my Facebook, so you have at least one guaranteed fan in me. I've been looking on Facebook from time to time for a DoomRL group, but nothing has been happening, I even considered making an unofficial group myself but I didn't feel that would be right. So, could a simple group or page be put up on facebook?
I would recommend a page, as it is more official, and requires less upkeep and spam-killing.
