If you wanna learn the chords to your favorite songs, this is a good place. But if you wanna correct some tabs & write a review, stay clear of a moderator named "NeoMvs". She is not the most respectful person with approving/disapproving corrections & if you make one little mistake she will talk down to you like a snob. There are a ton of people there who will talk down to you for making mistakes... accuse you of not being a guitarist or whatever. They are not very understanding.
If you wanna learn chords to your songs, just train your ear like they did in the olden days. It worked, & music was actually good back then.
