Alright I know what I am suggesting here would require alot on the programing front so it may be out of the question. I am a member of another PbP site (which i will not mention because I will not advertise for it here, if an admin wants to know I will PM them) that uses this functionality and I like it a lot.
Basically each game is kindda isolated within the site. GM starts a game, and people sign up to play (just like here with the want ads) the difference comes in the game itself: Player user names are hidden to the rest of the players only the character (or characters) name exists and makes the posts. So basically a player in 5 games would have a character name for each of those games, plus his user name (for use in public general chat areas).
This makes it easier (in my opinion) to remember characters and games instead of going to reply and having to ask myself "Alright now which character is St_nougat playing in this game?"
Also I would like the die roller to be a stand alone function within each game instead of the one here where another post is added or having to go off site.
Thanks
