I have worked hard on this site. And, I have been rewarded with lot's of permissions. Will I be able to keep those when we leave beta, or will I have to work to re-earn these rewards?
The point of having a beta is to build up a community that can maintain the site. To do that we need people who have a high reputation. That way these people can approve edits, close questions, etc. after the site is graduated.
So yes, you'll be able to keep all your privileges. We need you to have them so you can help us help you have them help us... (?)
NOTE Tshepang asked if your privileges get grandfathered in after a site graduates (if this was what you meant, sorry.) The answer is no. So if you have 1k reputation and the ability to edit questions, and the site graduates. You'll need to reach 2k reputation before regaining the ability to edit questions.
