Yes, you can take a print and post it in the "Support" thread.
Although this would work, it's wrong. We (the Game Masters) would highly appreciate if you just send the screenshot directly to us via PM.
To take a screenshot of the game, press F8. Then go to your files. Games>Toribash 3.[The version you took the screenshot in]. Then find the picture and upload it to a image sharing site. www.tinypic.com will work.
Then send us any other information of what happended. Then we can finally help you.
