Why can't I change my signature?

[Ewok 352]

I meet all the guidelines.. yet still can't change it.
It's done this for over a year, just haven't really cared that much until now.. 

I'd like this to be the signature: 

[JMUDirtyBird 25]

I can't even figure out how to change mine.   Anyone got any help?

I never got a response in the Welcome thread, so I'll ask here: how do I add a sig?

Click on your profile, go to account settings and at the left of the page it says signature, form there it's self-explanatory.

Finally changed it recently, but didn't see it anywhere at first.  Thanks for the reply though.
