Maybe there just isn't the playerbase for a new JKA RP scene these days. Everyone seems to head to the few remaining established RP clans, and those that don't have probably long since fled to the flourishing SWTOR RP scene. I wouldn't recommend sticking with the TOR -era if it hasn't worked out so far. After all, I suppose if people want to RP in SWTOR's time period, they'll just play SWTOR? Whatever era you choose, I recommend detaching it slightly from the movie era. That's why most RPs take place centuries after ROTJ - it's the same universe, but you're not bound by restrictions like no Jedi during the Original Trilogy or no non-canon Sith during the prequels, etc.
