Basically you want to go to your forum and look for a "signature" feature in your site preferences/settings. Then you want to see if it's HTML or BBCode that you need. Once you know that, go to the badge page here and copy the code you need and paste into the signature feature there.
It's quite a difficult task for a forum newbie. When someone asked for help on one of the forums I use, it was tricky to help them because the forum wouldn't display the raw BBCode we were using in our examples (obviously)...
(... screen shots would have got around this problem but we didn't think of it at the time).
TheWolfDragon, I would recommend you ask the cruze forum members for a screenshot showing how someone else has set up their signature. It is hard for pb or us users to help because there are so many different types of forum.
