I agree with both snag and rick.... I have never actually disagreed with a comment of yours that I have read... But either way, we all know how hard it is to apologise for whatever was incorrectly done...
In my opinion though, I would not refrain from somewhat critical posts as long as it is not a by-product of "personal problems"... Otherwise it is a faceless post with no real "brain" behind it... Thats my 2 cents though,
