Now that I cought your attention, let me first appolagise in case I posted this in the wrong section ( I'll kindly ask a mod to move this to the apropriate )
As for the subject. I've just stumbled uppon a great addon. It permits the user to search, find and join premade bgs / rbgs and It might be used for achievement runs, raids, instances, gold time challange mods etc.
Let's make this more popular. Great addon.
