A new feauture I came to think of:

In the "request a tab" section of this site one can only request a tab for a song or a artist. Why is that? There is alot of songs with the same titles but wich in fact is complete different to each others. I think there should be one song option and one artist/band option, not just a title option.

it is setup that way to prevent errors in notifications. If you put in an artist's name along with the title, if any tab is posted with that artist will cause you to be notified that your tab has been posted.
