That's a QuestionShark-specific feature. You like it?
I do like it. It's a little big, but I bet it helps to keep things on topic. We're not actively using QuestionShark right now, but I have some content in there so people on our team can see how it will look.
I can see that I'll have to do some stylin' to get it to fit better with our background. Likely not a big deal.
Well, you were looking for a fun little project, right?
Anyway, we will consider adopting this kind of thing for forum topics in the future, as well.
