As said, links to other people's sites are not permitted and I have removed a few for you and Ashley where you have conveniently linked to your friend's site for someone to go find something...like the pics for a signature. That's a no because you are now basically advertising your friend's site and asking people to go there. Discusssing an article and linking to sites that back up your discussion claim is totally different and I wouldn't think that it should be too difficult to differentiate between these two types of links.
