There is a lot of great advice in here! I'm going on my second FR and I did a informal one as well and a lot of this thread helped me for this FR. I plan on bringing it back to my chapter to help out those who never been through FR.
It is a good thing to avoid the "what year are you?" "what's your major?" "do you commutte or live on campus?" (commutter school here) I think by the end of the night they just want to scream at you bc of that questions...although it would be nice to get the applications before the parties even start to try and avoid those questions...but thats something we have to take up w/our CPH lol.
