So I have a question for you guys. I'm only familiar with 3.0 & recently 3.5 DnD, specifically the Forgotten Realms. But what happens when someone like myself shows up and people are playing in settings that are unfamiliar to them? I'm willing to learn, but I just wonder if DMs/GMs at these cons are willing to put up with people that are unfamiliar to the rules & settings. Do DMs and newbies go through a brief introductory phase (and everyone else waits) or what? I'm trying to get an idea on how to be prepared for a con or large meetup like this.
