How come the [img] is disable for the signature??? I haven't been in the community for quite some time and i have notice that it's now a hotlink instead of a [img]
Since we upgraded to vBulletin 3.6 we use the signature permissions and require that any images in signatures are uploaded as signature pictures. You can do this through your edit signature page.
It was disabled as some people were abusing the img tag in signatures. If you wish to have an image in your signature, then it must be uploaded to the site as a signature picture through the edit signature screen.
