vB3 had a signature plugin that when going over a specific height that you can set in the AdminCP the signature will be cut off when going over the limit. It won't resize the signature nor alter it as whole but rather it won't show the complete signature and just doesn't display the part that goes over the height. Any way possible someone can create this for vB4?
