While there can be a trickle of new players from other MUDs via a site such as TopMudSites, I think there's more potential in people who are interested in fantasy/RPG maybe in other ways currently. In general a big target group should be people who enjoy reading fantasy novels (since reading is pretty much what playing CF is), and how in this game they can become a hero or a villain themselves in an interactive storyline.

In the Top100 at RPGgateway there are many more types of sites rather than just MUDs, so it seems there could be some potential for growth there.

Oh and for the imms, the RPGG voting button is still missing from www.carrionfields.com (it's only on the CF Forums site):
