Fill out your information as accurately as possible. Please choose a PG-rated username, you never know what 12 year old may be wanting to trade for your old copy of Mega Man.
Gamecycler uses Gravtar profile images. Please make sure that your Gravatar account is connected to the email address you enter if you want your user profile shown, otherwise it'll be a generic "G" for Gamecycler. And let's be honest, most other users probably want to know what you look like if they're going to trade games with you. Or at least see what NES avatar you use to represent yourself. We'd go with Little Mac from Mike Tyson's Punch-out, but that's us.
*IMPORTANT*Please make sure your mailing address is accurate and at a safe location. Other users will be mailing you games directly, and it's really important that your game doesn't end up somewhere down the street, because if a copy of Fallout 3 randomly found it's way to our door, we probably wouldn't want to return it, so we wouldn't expect some random guy on your block to do it either.
