Help Modding

[UnexpectedAnvil]

I would like to mod a game between me and some of my friends. Most of my friends have not played any forum based mafia, so I will probably be running a newbie type game. I have played mafia a few times before, albeit not on mafiascum. The game will only be between me and my friends. Here are some questions I have:
1)What website should I use?
2)What set-up should I use (I am planning to play with 10 people)?
3)What other tips do you have for me?
