1. You tried to copy MKW.com and completely failed.
2. You stole the banner.
3. You stole a member's avatar.
So close this shit down, go to http://www.mariokartwii.com/, apologise and maybe we'll let you join if you want to. So yeah, the MKW.com admin knows about this and has the right to sue you if you don't close this place down. Good day sir.
