Andy, One of our registration heads, has written up a brilliant guide on what to do, what not to do, and what to have ready and with you for getting your badge Friday morning. Everyone should read his post and every reply he has written in that forum post. If you manage to read all the information in that forum post and you still have questions feel free to reply and ask.
Friday morning will be extremely busy for Regisration and if everyone reads his information registration will go faster for everyone. Don't be the person holding up the line because you didn't take 5 minutes to read the information.
