I don't think it would be much of a hassle. Usually (not always though) I have either a lot of time or no time at all. That's why sometimes I'm not able to put up a post for days, and then you get a textwall with pseudo-clever bnc thoughts ;-)
So yes, I think I could play a second character. If you want, of course, you can first ask other players whether they want to join, but I'd be happy to introduce MacC. Yes, it is per accident that both characters end with c.
Something else; I'm not sure who do you mean by "K"? I guess you don't mean Krestov, since he's not absent. So who exactly is bnc to write?
