Disable chat room notifications for OSX Messages?

Question

In the Mountain Lion Messages app, is there a way to disable notifications for chat room messages, but still have notifications for private messages? (this is the default behavior in Adium)

Answer 1

With the chatroom thread selected, uncheck Use Alerts in this Conversation from the View menu.

The is the best solution I've found (only disables notifications on a per thread basis). I haven't found a global setting that disables notifications for all chatrooms.

^{I found the solution from this answer on "How do I temporarily disable or mute Messages (iMessage) on OS X?"}
