I agree with lmckenzie in regards to alot of people here are hobbiest and work on their galleries with pure enjoyment.  I have also gone to art school, of course that is when dirt was discovered so it was a while ago, but the basic truth still remains the same, those that ask for only positive comments, should be respected to the point that they don't want critisim, that is fine. 

I myself always want to learn, so I do want critisism that will assist me in going forward, so really to each their own.

To bad though, can you imagine how amazing some galleries can be if they just learned more, including me.
