that's great! today on the Kalt server, we had a human pyramid, with everyone armed with rockets. As soon as the pic was snapped, two people let rockets off right into the ground. It was horrendously awesome!
Open the file in photoshop, then click "file" "save-as", name the file, then click JPEG as the file type, then ok, then ok again, then upload the pic to photobucket and copy the "IMG" code, then go to your sccount setting on this website and where it says "signature", put the IMG code in there
