The first thing you probably want to do when you register is to find band-mates, producers, collaborators et., to help join your band or start producing with.
The 'Advanced Search' function lets you specify the search criteria; such as 'Genre' 'Post Code' 'Instrument' etc.
There are two ways to do this.:-
1/ Via the link in the 'User Area' menu
2/ Via the 'Friends' tab drop-down menu
