Ok, so here's what's going on.

If you use the "Basic Editor" in your UserCP->Edit Options (http://www.jazz2online.com/jcf/profi...do=editoptions) then you don't get that option for some reason. This appears to be a vB thing as I found some mention of this problem on another forum when I searched for it. Change your editor to be the "Standard Editor" at the bottom of the above page and that should fix it.
