If you don't know the difference...
Beta is we give you suggestions on how to make it better. As you are the creator/editor it is up to you if you use all or part of our list of suggestions.
Review is when we give it a score from 1-10, 10 being greatest. I don't think we ever had a 10, but I have heard rumors lol.... We are very nit picky even in the spelling on your briefing/notes.
Like hoz said, the less addons you have, the more likely it will be beta or reviewed. I am boycotting ACE and their team and I have not had friendly confrontations. Hope someone else will jump on it.
