ok man, if you were a good little noobie you would have read the stickies and known to post this in this thread:
http://405th.com/forums/index.php?showtopic=12649
but, i have wondered about this too, so post this in the link I provided and see if someone can answer you. most likely a moderator will close this up, so like i said, be a good noob and read the stickies so you don't get an infraction (if that word was too big for you it means a warning)
