One of the best places I’ve found for online artist connecting and art discussion is Robert Genn Twice Weekly. http://painterskeys.com There you sign up for the newsletter and it comes twice a week to your inbox. The first thing I do on the days it arrives is turn on the computer, pull up my email to find out what’s new and what comments have been posted. I also have his book “The Painters Keys”. A must have for your art library.
