Sometimes I've come across some epic comments from people on the forums which, if I've had the space, I've put in my signature for a while. Regrettably, I've run out of room to put a couple of other links I want in there, so I'm going to put them in a thread instead. If you've found any other excellent ones yourself, please do post them.
