Okay, I've done #5, but it was in a RP I was supposed to be more than one person in. ;-) That's insanely hard. I had one reciently, I was 3 people in. Toola, Kali, and Aayla (Toola's baby).

I don't see #18 and 19 as being "wrong". We do that all the time in Chat for our RP group. Mostly, because of the diffrences in time zones with some of the players. Such as, "It's 2am. I HAVE to go to bed." ;-)
