I can totally play a leader! I've got an idea that would be a good fit for a bard or a warlord. It works better as a female character. I'm trying to come up with a male concept for a leader as well; some success. How are we doing as far as the requisite two female characters (or is that specifically players)?
Anyway, another two things; I also have a pretty good knowledge of 4e, having run it for a significant length of time. I can totally help with the creation of characters, or the asking of questions, or whatever.
Secondly, I'm going to be terribly busy the next few days, and won't have much time to work on a character. I'll keep an eye on the thread, though, and keep those thoughts going!
