All of your reasons are valid. Except this one. I witnessed Joe Pavlik get evicted from the Wednesday trade session because he was not preregistered. Joe is a fine longtime member. He forgot to preregister. He is known by everyone in the club. If you remember he ran for club office.
As individual members we pay a lot of money to get & be there. Not to be able to participate over that technicalily does stink. As far as doing away with the Wednesday trade session. If that would happen I would do away with attending the convention as would a few other members that I have talked to. I think this rule should be amended to allow members to attend any Wednesday function. That is my belief & I am sticking to it.
