Whoa!... moderators who are non-Cakewalk employees ?!? - This is quite a "first" after over a decade of the "CW employees only" policy! That's a big move. (Insert eye-popping emoticon)
After reading through this thread, one thing that stands out for me are the posts and comments about potential new mods - posts about suggested rules to keep new mods from abusing power, comments regarding methods of redress for members slighted by the new mods, concern about members' ability to appeal to CW Admins, and many more related comments. Now some of the posts may contain great ideas, but what stands out is that many forum members seem quite uneasy about CW's decision to use mods who are essentially peers. Most everyone is saying "great idea, more mods", but many are also qualifying their support by asking for rules and restrictions on the new mods, and the concern is significant - members are clearly worried about being treated fairly. Of course, it's CW's prerogative to implement new mods and to make the rules governing them, but the undercurrent of concern from forum members about being treated fairly is palpable.
CW may be entering a situation where they are damned if they do and damned if they don't.
Which leads me to a suggestion - start looking for volunteer mods within your beta test group - at least there is a degree of commitment and loyalty (if that's what you want) there among your beta testers. You may even find all of the volunteer mods you need there. (Disclaimer for the cynics: I am NOT a beta tester).
If after that you still need more mods, start with members like scook, who's post count must consist of 99% helpful posts. The general membership seeing respected members like that being promoted to moderator many ease some of the concerns of anxious forum members.
Or, you could make members really anxious by choosing members who have post counts consisting primarily of inane posts in the Coffeehouse about bacon/some guy named Fred/upstairs-downstairs/other limited-intellect content.
