First of all you need 10 post(s) to be able to post links (That's when you get your member level 1 tag). This is to prevent spammers / bots from advertising. You can use Imgur to post screenshots, of your hack,trainer,hack ingame. and for virus scans you can use Jotti & Virustotal. You should provide two virus scans of the same .rar / .zip file.
You can also read my HOW2MPGH guide for more basic info about MPGH, and reading the rules of MPGH would hit you on the go to stick around.
Welcome to MPGH Blunt, will be glad to help you and see you contributing to the community.
Have a nice day.
