I'm involved in Con Amore, and Rosae Dormientes. In Con Amore, we're still trying to track down artists (which is an absolute bitch to do) and work out each character's specific route, so the slog of actual production hasn't really started yet. Rosae Dormientes is really floundering right now. The founder left all of a sudden a few months ago, which caused the then-devs to actually make another site. I don't think they've picked up the steam they had previously again. So they're not at full production either. So that's how I manage that.
Once both projects hit full production, it'll be tough, but I think I can manage it.
For those of you who don't know, Rosae Dormientes was previously known as ShinVN, which pissed off Worth by posting about the project during MS's open recruitment stage in the old forums, which was very rude. I was still looking to join a project though (this was before CA), so I checked it out for the hell of it, and applied. At about that time, their leader, GrimAngel, left the project without a word and there was about of month with no word from the devs. I ended up starting Con Amore in that time, and eventually ended up getting admitted with RD after they got a new site. So that's how I ended up in two projects. We'll see how it goes.
Oh yeah, I'm also involved in MS via nefarious mind puppets. So there's that as well.
