Cyber's idea is what mafiascum does. They prod you in a private message if you haven't posted in the thread after like 2 RL days, and then make a post IN the thread that the person has been prodded.

Only thing that's good for is if there are replacements, which there are plenty in mafiascum. Here not so much.

Mikey's right though. If you can't dedicate at least one "thoughtful" post a day to a game, then you really shouldn't be playing.
