i use it to get a grab on some guys i really apprecite! You know the drill: after 3 months, you don't remember the nick name of that guy who did an amamzing job... This way, wherever i need them, buddy list here we go
I have around 20 on there, and normally check the forum homepage if i want to see who all are online. My buddies will be in starting of the online list.
I have a select group of people I stalk ...i'm pretty sure they know who they are, well most of them.
