If you don't mind horror, maisondeportes has a very easy AC of one proof per month, which can either be a post or a thread, however you prefer to play with it. It is a prose-based game but is comm-based, and is on the slower side, and very backtag friendly. There's also a lot of plot to get involved with if you'd be interested in that, but how involved you get is completely up to you.

There's not a DA cast there at the moment, but I'd personally love to see one there again, and I'd be happy to answer any questions you might have about the game. So do let me know if you do!
