I have an idea for a Mowgli/Tarzan-inspired Dawn or Zenith Caste that I want to try out but there are no 3e games here.

Yes please. someone run.

I've been running Exalted on this site since 2011 and with the exception of one group of players that have stuck with me, most games don't survive beyond a few weeks (but that's the case with most games on here, I imagine). I don't have the energy to go through all of that again as ST. I would love to play at some point, though.

I'd play, but I am in no way familiar with the rules for 3rd so I can't run. Charm rules are always complex so I would want to run until I had at least the basics of that down.

 And your right most games die quickly on RPoL. Mostly because it takes a good chemistry to play and not step on toes.
