I'm fortunate to know just about all the moderators (re) joining ranks with the department and I am very confident in saying that they're the best for the job, proven either in their past work in moderating or in the dedication and positive attitude to and on the forum.
Just because there are positions available doesn't necessarily mean James and Martin have to open applications. In the event that capable moderators can be acquired through other means (in this case former staff returning) I see no quarrels swinging that way.
