As for me, I think you should accept chembake back into the forum. We all know what he is like, but were willing to accept a little "sour" for the occasional "sweet". I think he has done an invaluable service in many ways to this forum and has offered many insights. I would like to see pictures along with some teaching moments, but if he doesn't want to do that, oh well, so be it. The tag line for this part of the forum is that overt criticism is allowed, so is it or not? Let him criticize if he wants to, when he feels someone has done a good job, he states it. Sure, it's few and far between but it sure means something when he does compliment (I for one haven't had any!). Anyway, I think he should come back, sour and all.
