the data stream for oQueue comes from the group finder.
try clicking the clear filters button in the lower right and selecting 'raid' as the premade type. does anything come up?
only raids from the group finder :(
if you're seeing raids.. then the group finder data feed is working.
if you're not seeing groups in other categories, that's because there are none on the group finder.
the group finder only shows groups from a small subset of realms, not the entire region.
we're working on something that will address this situation. if all goes according to plan, we'll be making the beta available on the site today
