I'm not sure of a better way to word this... On my site I'd like to host various contests, and as a little bit of a reward for winning the contests, I'd like to have like a little banner underneath the user's name whenever they post, like their title. I'm not sure whether this is even possible or if there is a MOD that will do this. Any direction would be greatly appreciated.
Here's an example of what I mean:

They're underneath the rotating shapes which are like the stars on here for the post count. There's some on Pyritie, Elenai, and Dionesiist. Those ones are rather small, but that's similar to what I'd like to do. Can I? Is there a MOD somewhere out there for this?
