So i was wondering, what are some of the more popular content management scripts on the market right now for adult paysites?

I know about MAS and SiteDepth, but what are some others that are around, whether they are used by a lot of sites ot just a few?

Im trying to get an idea of their functionality and how much is charged based on the functions these scripts have so i can price our custom solution competitively should we decide to go ahead and start licensing our product.

Regards,

Lee
