Whether you are just learning, a professional, or simply interested in Art and Artists, then you absolutely must visit the most outstanding cyberforum for Artists, http://www.wetcanvas.com!
Started in the late 90's and now with nearly 150,000 registered members (registration free) and nearly 7 million threaded posts online, this site provides a veritable grab bag of resources for artists and art lovers, with channels that specialize in virtually every conceivable area of art and art medium.
The friendly, civil and community spirit of this site is maintained by no tolerance for impolite, rude, discourteous or unfriendly behaviour on the part of its users. Thus, it fosters a friendly, but intellectually challenging environment for discussing, displaying, learning, posting, producing and viewing the works of artists of all levels of experience and styles.
Channels offer subforums with Classrooms, Discussion, Critiques, Help with quesions, Demonstrations, and more. The major channels are listed below and guests can browse all they want without registering. But registering, providing only the personal information you wish to share is free and allows you to interract with one of the most interesting and helpful major forums on the internet. (And I have been using the internet since its beginnings in the pre-WWW days!). This is the ONLY place I have ever felt drawn into posting and interracting in a forum.
Having come to art late in life, I have learned more in less than 6 months on this forum than in nearly 8 years of reading and self study.
If you are interested in Art, this is a MUST SEE site!
