Thanks for posting this link, just what I was looking for for my teenager.  He has zero interest in building machines, which is my thing, but loves his keyboard time.  By the way, I really love this forum, I'm a member of a few similar site in msn/communities and this site blows all of those away as far as features & ease of use.  You guys are doing an excellent job here.  I've sent your link out to a few folks I think will find they also like this site very much.  Keep up the good work!
