I've processed more than two thirds of the "waiting" list for Greek (el, not el-po), but I'm seeing no changes in my test blog. When are they supposed to take effect?
By the way, not as simple as I first thought... Approving correct suggestions and discarding or correcting mistaken ones is easy, but I keep finding alternative translations of the same term or of similar strings. So I have to proceed slowly and carefully, filtering for all instances of each string (including "current" items) and trying to standardize things.
