How about making some kind of News Board, where all the testing being done by AG is put up? This way the users know what's going on and they might complain a little less about all the glitches occuring on the website? This could ease the moderators workload a bit...
I dunno. A few mods and admins, aside from most of the crew being friends and family of the staff, will be beta testing, so I'm not sure if they can relay the info themselves. They are probably on a hush-hush oath, where they cannot reveal anything about AG3 as to not spoil the surprises.
And then there's open AG3 testing....not sure how that's going to work out....
Well the open testing will be just to see how the site runs with more people on it, also there is a great deal of chance that more people will be able to catch small glitches missed by closed betas.
