I'll admit that I was initially not in favour of your training suggestion, and in the form you were proposing I'm still not. But I can see there could be advantages to moving at least a little way in that direction. Perhaps new reviewers could be encouraged to carry out their first few reviews in tandem with an experienced reviewer? So far as the underlying philosophy of GA is concerned, I very much share G Guys view that it is an attempt to get as much of the content up to at least an acceptable standard as quickly as possible, so I'm just as much against the GA as FA-lite move as he is. The more articles that can be processed, the more editors will see what that minimum acceptable standard is.
