So I downloaded and installed oQueue after not having used it in quite a long while. It loads fine.. except there is no mesh button, no submit tag button and in general the addon just sits there doing nothing.

I've searched for the issue and for a general FAQ but come up dry.. anything I've missed?

with patch 6.0 Blizzard pretty much killed battle.net addon data communications so the cross-realm mesh is impossible to create...

for the status before the patch hit us...

at the moment Tiny is trying to transition oQueue into an interface for Blizzard's grup finder using the limited API available... give him some time, and maybe a few beers :)

Ahhh thankyou, that explains much.
