Er, never mind. I mistook the links in the above reply for part of your signature rather than useful parts of your post... so I expanded on the 'amplification' comment. As it turns out though, those links are better :)

It pays to look there first. Once you have 50 posts and 30 days membership you can even write or edit library articles!
