There's big changes coming here that will allow this. We're going to change up the forum software and allow a lot more things. We're just in the middle of making sure it doesn't lose everyone's information!
I suspect this will be ready in a couple of weeks. Stay tuned!
Sorry, it's coming. I'm using another site as the test, and when I get the kinks worked out, it's on here! Should be soon actually, though. We're very close.
