Im sure there is a perfect reason but......

Now im sure this has already been brought up (or at least it should have been) but how come the vb [ img ] [ /img ] code is disabled in the profile signature?? is there a reason for this?
Dont take this the wrong way i dont mean to sound ungreatfull/petty but is there any chance in getting some sig banners up? Anyone in the know???

The reason why I disabled it, was because some people where abusing it, and putted banners of their website, and spammed wbw..
