Fixes forums by removing avatars, off site images and signatures from sites with the word forum or vbulletin in their URL. Seems to work quite well with vBulletin and phpBB sites.
This extension is not intended to remove adverts, though it might have that side effect at times. It is intended to remove the clutter that some people feel the need to add to their posts to make them more individual, when in fact all that they do is make the forum harder to read.
It is a simple extension - now with basic options to make it slightly more than an all-or-nothing deal. Future versions could add different avatar and signature matches.
