Disable world chat for 30 minutes

world ‎1‎:‎10‎:‎02‎ ‎AM silkcomLOL - u all remind me that i still need to add the "disable world chat for 30 minutes" option

Occasionally, a very heated discussion ensues in world chat: heated to the point where multiple people get warned for harassment but the discussion continues. Disregarding the specific repeat offenders since I assume they're already being handled appropriately by the moderators, it would be useful to have the option to disable world chat for a set amount of time - 5, 15, 30, 60 minutes. I could see this working in one of two ways: either a per-player setting (instead of disabling world chat and remembering to manually re-enable it later), or as an option mods could use to let everyone cool off a bit.

Personally, I prefer the latter option, since while the former option is certainly helpful, it does nothing to diffuse the situation. On the other hand, muting all of world chat for 5 minutes (or longer, if necessary) can give everyone time to cool off and find another forum to flame. This would not affect the help or trade channels, so should not affect game play.
