First, I want to mention that I am sorry that JohnV will be quitting. His posts have almost always been informative, and to me, there's a warm fuzzy feeling when you have a moderator or administrator answering your question, because you know that they have a lot of experience fielding many many questions.
Second, I was puzzled as to why his thread was closed and locked, but I'd like to open this thread so that other members can come in and say their thanks for JohnV for his tireless efforts
Third, Dibrom had complained in another thread that he is now the only admin left, and that he's too busy as IS to work on his to do list and field all the complaints/suggestions by them. I wonder, then, if it wouldn't be too inappropriate to suggest other users who have shown themselves to be well-behaved and insightful. Those users might be worthwhile to become moderators. Unfortunately, I can't think of any who aren't already developers (do developers have moderator status?).
