Yeah. I noticed that too. Hold on.
EDIT: Its now working. Had to tweak a few things. What I did was I uploaded one of the button pics that is found in the link provided earlier in this thread, then I added it to my signature, then I selected the BBcode that you'll see in the box where you create the signature, and then clicked the linking icon option and pasted the link into the option box, then clicked the "Okay". Now I have a clickable image that is linked to my Raverly profile.
