The idea is to allow the authors to attach up to N (3?) co-authors to their tabs. It often happens that a tab is an effort of several people, either from the very beginning or as a result of corrections.

Co-authors will be listed on the tab page, they will also have a separate list of the tabs they co-authored on their member page. In addition they will get 50% of the tab's scores (the author will still receive 100% of the score).

This is just an idea, the purpose of this thread is to discuss it.
