How to auto ask user if some one wants to add them as a friend

[T3MEDIA]

When a user adds you as a buddy I would love vb to PM the user stating username wishes to add you as a friend. (the difference is a buddy is them adding you and thats it. a friend is you accepting them and adding them as a buddy to your list as well)

once you click on a url in the pm it goes to the standard add buddy link with their name in the box and you accept.

if you say no you do not have them as a buddy and they just have you on their buddy list (like normal)

Hi5 Friendster and myspace does this already just would love to see vb using this.
