Probably having a moment of complete noobness - but how do I get rid of all the messages coming through HUD about what ever one and creature in the world are doing.
That would be Witch hunt. I believe its catagorized under Timers. You could also just check the Add On list towards the end within the Mazzle UI Config. Simply turn it off and reload UI. If you still need help I can post a screen shot of it.
Another solution is to type /wh then change it to display "none". I expect that theres some good functions of witch hunt so I haven't turned it off yet in case I decide to go through and look at them one evening.
