@MikeRigsby I wouldn't worry about not knowing everything there is to know about all things IT related with this group. There will always be people who are freakishly smart when it comes to IT and you'll wonder whats wrong with them and then there are those who will have less knowledge than you...maybe they think you're freakishly smart? In any case, let just all get together and drink beer after the day ends and we can all compare technical knowledge and have some laughs. That's the best part of The Krewe is you don't have to worry about your experience or lack thereof.
I would advise that you watch out for those European Krewe members though...they're always up to something...usually no good.
