Thomas, that's one of our PermaThreads, that's being edited and preserved as a permanent reference. You'll find links to the PermaThreads in the Mudcat FAQ. Other PermaThreads are Rick Fielding's guitar picker guide, and Bert's "What's On" calendar, along with guides to song circles and HTML and a Scots glossary, and a couple of other things. You should go look, no?
