Just an idea. How about putting a nice little forum under the General Discussion list for Free MMORPGs. It seems like every other day I log in there is a new post on one of the boards for advice or information on any free MMORPG's. I've seen a wealth of information come from many of the site members on this topic and have even looked at the game list you have available. I don't know if this would help cut down on all the "Does anyone know of any free MMORPG" posts or not, but it might be worth a try.
