What channel is all of the chat spam in? I'd like to move it out of the first chat tab but not lose it, if possible.

You shouldn't be seeing the channel as it should be hidden by default. 

Anyways, it is listed under Global Channels as oqchannel. 

I think the "spam" he refers to is the raid announcements. It looks like the code uses the default print API so there's no logic to redirect that to another tab and unclutter the General tab. It would be nice if logic similar to that in Auctioneer could be used to redirect that to the named tab of one's choice. (For example, I create a Trade tab for trade chat and redirect all Auctioneer output to that. I'd love to be able to create an OQ tab and tell OQ to use it for output.)
