War ended (somehow? doesn't matter) and Lily and James got divorced. Harry is a young kid/teenager/pick an age. I'd be up for playing either Remus or Snape hooking up with Lily.
I'd also play Harry or Ron against Ginny or Hermione, although I have no particular plot ideas jumping out right now, although if you tell me what kinds of plot lines you like, I might come up with something. Remus/Tonks could also be fun -- post war, trying to make their relationship work after they jumped in far too quickly and had a baby right off.
My rp email is remus.loupgarou@gmail.com. Let me know if you're interested in giving anything a try.
