All you need to do to hack that site is we all get on at once and hit refresh over and over. LMAO.
501 users on the site at the same time is enough to crash it. I guess they use the same developers as MS-NBC.
Try SQL injection. Type a semicolon followed by SELECT * FROM USER.
If they haven’t coded to preclude it, this will cause the server to list all user information. Of course, the table name may be different. If it returns a programming error, try replacing USER with NAME or some such.
