Pete-
While I agree with you that many umpires have gone to "private-public" forums, times have changed. Instead of asking others questions (and getting the smart-a** comments from some of the posters on the other sites you travel) we can look up many of the scenarios with an easy search.
My biggest complaint on many of these forums is the attitude that is projected. You cannot expect someone to post a question, get berated for it and then think he/she will stay a member.
