Somtimes people will find bugs in games. What if a non-member finds one? There could possibly be a Guest Bug Reporting account that all AG users, even non-members are allowed to use, with the password being known by everyone. I was also thinking about a hacker and bug account similar to the AG archive with a bug/hacker reporter. The account name being Guest_BugReport. The only thing off limits being changing the account. (Only Admin./Mods. could do that.)
The account will most likely be abused due to how many people on the Internet act. Cenere is right here, if a guest on Armor Games does find a bug/etc., then it's best to use the contact page or GetSatisfaction. Actually, they should have a link somewhere in AG3 to GetSatisfaction since not so many people know about it. That, and I'm sure it isn't difficult to create an account on Armor Games to report something on the site.
