as a moderator i read( nearly) every post and i can't see any posts that are disrespectful to joe. disagreeing with some one or asking them to prove a statement is not disrespectful it's just normal discussion.
calling him an old codger is not disrespectful, it is forum banter, Easter bonnet ( or what ever his name is now) is often called a lot worse but no one jumps to his defence.
but we all have a choice, if joe doesn't want to participate in CIU then that is his choice, I have forums that I choice not to participate in... I just don't log onto their site I don't need to make a big statement about leaving by deleting my membership.
hopefully joe will reconsider, CIU is a better place with him here.... just like Colin, Simon, Dawg,darren etc..etc..etc make this a better place. diversity always enriches these forums.
