geeDub: How do I edit my friends list? (on mobile till I get back to my office next week)
It's tedious as it is on a PC, can't imagine what it's like on a phone. I'd wait until you're at a PC. The fastest way to cull your friends list is to go to your profile, expand your friends list, right click on a player and open the page in a new tab. Do this as many times as you need to and then go to each page, delete the friend and close it. ( If the "delete friend" button is missing, refresh the page.)
