Well for first timers there are a couple of rules.
1. Make your hotel reservation - Thats it we ask for a headcount in January so we can see if we hit 100 this year.
2. Bring many large bottles of alcoholic beverages for the parking lot party on Friday night (yes if you show up Saturday you miss alot of the fun)
3. Stay away from Tom and his "Friendly hug"
See you in Austin.
