You mean like bigboards but with ranks for those options? I don't know of any personally. However there is a nice new directory called thebiggestboards.com
big-boards only ranks by "post/members" ratio. I'm launching a new site called www.BoardsMD.com that ranks forums by Health Score. The site uses a proprietary algorithm that weights each diagnostic such as reply odds, reply rate, viewing odds, activity average, etc. as well as GRP, members, etc. to come up with an overall health score for that forum. You can CheckUp, MatchUp and BattleUp multiple forums. You can also see time charts of how the forum performed in each category over time. I was asking this original question because we have been unable to locate any other site that is doing what this site now does. If you fine any site or if you own such a site, please post a comment here. Thanks.
