Some thoughts from someone who just discovered this site. Kudos to the creator and contributors of this site; it looks like an amazing collaborative project. It's people-sourced resources like this that make me love the internet. Congratulations to all on the purchase. My wish, to the new webmaster, is keys for the tracks. Without them, as a beginner, I don't want to use the tracks because I don't want to guess wrong and train myself to play in the wrong key. I'd also love to be able to search tracks by genre. Best wishes, and reading the article on UG, it's great to know that this site can still continue.
Edit: One more observation. I just got stopped by the captcha required to post here, because I missed the domain question. Perhaps this site, because of all of the content held in it, is a target for schemers, but I'm used to the captchas going away after logging into a site, making it easier to navigate.
