I was clicking around the 'user control panel' and noticed that the 'manage friends' and 'manage foes' were switched--
When you clicked on one the other would come up.
Idrc, but just found it interesting.
Kinda felt like finding a secret treasure or easteregg V('—')V
Really? That's curious. I just checked myself and it came up fine for me.
Also- for curiosity's sake, is there a block separate of foe?
I think the foe functions as a block. I don't remember there being a separate block feature, since by adding someone to your foe list, it essentially blocks them (except from PM'ing you). Is blocking from PM'ing what you're asking about?
