Mar, this may be pointless info for you as you might already know, but I want to just share my mistake in my first hosted game (about a month ago).
I got a PM from the mafia asking me to kill noodle. I replied and said "noodle is dead, he was the busdriver". The LAST second of the day the doctor chimed in and said "I choose to protect noodle tonight" DOH. Also, the 2nd night I had a similiar mistake with a busdriver role. Wicked was a cop and asked for a persons role. I pmed him the response. then the busdriver switched that person and I had to send wicked another PM being like "i made a mistake.." luckily wicked was nked haha.
BOTTOM LINE: Make sure you get all the activity that could affect an outcome before you reveal roles or alignments. again, couldbe common sense, and I defintely messed it up by being a little over anxious. Just my two cents.
