As demonstrated below, go to where it says 'Add' and the Forum Myspace gets a request from you wanting to be their friend. Then they get a choice of approve or deny.
Where it says 'Click here' is where you need to go in order to do it.
It may be different here but in the other Sakis Myspace in the box where it says 'Add to friends' or 'Add' or whatever, do the same.
NOTE : You have to be a member of Myspace before you can do it though.
