Who approves suggested edits if no one has 500 reputation?
Do the edits just stack up until someone crosses the threshold, and then they have to go through reviewing all of them?
We do, from time to time.
It shouldn't take too long for a couple people to get 500 rep. Until then, though, we'll approve what edits we can semi-regularly. I took a look at the queue just now, and it only had three edits.
