Hello CanadienneBacon.
I've played several PbP games here on ENWorld before, but I haven't played since like a year ago. I would like to start playing again, and I'm exactly looking for a relaxing low-key game, not much because I won't post often, but rather because I would prefer not to have to worry too much about character optimization. Combat is fine, and I definitely try to do useful effective things when fighting

but I typically want to design a character that makes sense as a whole rather than min-maxing. Just to clear it up before I even apply to your game
I have a Human Rogue character which I played on another adventure here on ENWorld, the adventure lasted only about half a year and then died out (actually, it was the second longest-lasting PbP for me, I'm not lucky in picking up PbP games). I would like to be able to pick up some of my previous characters and re-use them in a new adventure, but usually this idea is not accepted easily by the DMs, who prefer brand new characters.
Let me know if you think this is acceptable... You can read the character description here:

and the previous adventure she was playing in:

The character was 1st level, but upgrading it ro 6th is easy. It used only 3.5 core material. It was actually designed with 25pt buy, but I guess she wouldn't mind having to get a bit of a boost
OTOH you may well have a problem with her background and with the fact that it may assume certain things that don't belong to your setting at all. In that case let's consider how much it would need changing: tweaking things is not a problem, but rewriting her story completely is not worth (better write up an entirely new character in that case). If the fact that the previous adventure was set in Planescape is a big issue, we can even go as far as assuming that it never happened.
Let me know what you think.
