the positive aspect of session .org is the resources of sheet music.

as a medium of discussion it fails like many internet sites, because of some of the people that use it who are either negative and or argumentative, and it fails because there is no body language as a means of communication
I know of two people who used it who were in fact beginners but contributed as if they were experts.
I am not refrring to Michael Gill, who by all accounts wasa very competent musician.
The strength of the site is the sheet music resource, this very day i learned a tune 95 percent by ear, but used a sheet note transcription to get some fine detail, that was eluding me
