This is simple. You just try to type your username with a different body part than your hands, like nose, chin, elbow, etc. NO INAPPROPRIATE CONTENT! AND NO SPAM! Then, you list the body part you will type your username with. Then type your username with that body part. And you can say Put-ups (positive comments) but no Put-downs (negative comments.)
Did it! And if you're wondering about the capitalization, I just pressed the "caps lock" key, typed the letter that needed capped, then pressed cap lock again to turn it off.
