Actually, the editor selection and training process is temporarily on hold, as stated in the OP.
We have taken on around a dozen trainee editors for LTB and, after investing considerable time in getting them started, coaching them and all that (which slows down the actual editing), we've ended up with just a couple of regulars. That is terrible ROI.
The reasons are various, including people with real potential not bothering to read the instructions and screwing up.
We're rebooting the selection system and revisiting incentives to attract better editors and discourage time-wasters, even before the new editorial system is built out.
I'm locking this thread, at least for the time being. Watch for a new one soon.
