I don't want to start a flame war, but this does seem a bit precious to me. It's not like the charters wrote the songs or played in the recordings, and often they've used tabs created by others. Yes charters put a lot of work into making CDLCs, but I don't think there should be a problem with making available a CDLC made by someone who isn't on this website, unless you're also going to prevent CDLC that wasn't uploaded by the rights-holders of the actual song! The 'original charter' should be given credit out of politeness, but the idea that a CDLC is "owned" by the creator seems at odds with the fact that the "creator" doesn't own most of the content of the CDLC, and it's all provided as a gift to the community for educational purposes. The administrators of the website can obviously dictate whatever rules they wish, as its their website, but this does seem oddly inconsistent to me.
