Hey, just a quick question about the chat. How do you unmute somebody? I've got four people muted and I don't remember what most of them did at this point. Besides, muting somebody forever seems kinda wasteful if you just want them to shut up for right now.

Shoryu is correct. You'd have to chat with the guild mods to get them unmuted, and it typically takes doing something rather bad to end up on that list in the first place. Think of it as a public display of who's been effectively banned from doing things there.
