We haven't had to worry about this as of yet, but I wanted to point out what is legal and what is not when it comes to posting TAB.
"Author's Interpretations", or when you see stuff posted on TAB portals is perfectly fine when you post TAB - those are not copyright protected.
Also, stuff like SIN posting his own TAB, or exercises posted, those are fine as well.
What is NOT "acceptable" is to scan official TAB and then post it - that is a copyright infringement that will open up a can of worms if it is spotted by a publisher or author of it.
Like I said, nothing we've had to worry about yet, but it could be an issue down the road. Just for everybody's info. [img]images/smilies/icon_cool.gif[/img]
