Grobbak should put a big CF banner ad over all pages.

I think drawing a well told CF-related story, based on logs, for example, would be a good idea to lure in roleplayers who enjoy a good story. Random gags could also be entertaining, but they are not going to have as good bringing in power in terms of roleplayers as a well told story. Trying to get the comic visibility via link exchange with other webcomics and such isn't a bad idea either.
