Yep, I'm familiar with Clarence as we did some correspondence when I was on the board. I also like his technique and his points are valid regarding clubs not being too active with newbies.

I don't have an answer when it comes to "non-welcoming" attitudes at any particular club. If members can't see benefit to welcoming and helping newbies, then I suspect the longevity of that club will die along with their members. It certainly wouldn't be much "fun" playing in a club like that.
