I'm sure you'll meet lots of people. The last 2 years has featured a "meet and greet" on the first night, a social hang-out, food, drinks, mingler games, etc. Last year they had a session for 'newbies' on the first day to help people get their feet wet, meet new people, etc. I'm not sure if they're doing that this year as they haven't announced the schedule yet. Check your e-mail for updates as they're announced.
Where are you coming from?
