RP rules were not even a subject in the matters that lead to the massive loss of members, as I recall. It was more a matter of everybody really disliked Dark, his actions, his character, and so on; also, the matter of him turning the site into a gaming site more than a RP site was none to pleasing.
As for RP community, they seem to be inactive. Most of the Rokkers seem to be either playing games, revitalizing their RP-world-thing, or role-playing at GamerIsle - for god knows why since I thought they hated that place. Gath, Kamica, Arafor, Zan, and RpGal are still with us, however everybody in general seems to have gone inactive ever since the summer started, myself included. What little time I do have I'm usually working on projects for Xlightscreen's site or developing other RP concepts that are structured for play on multiple sites.
