Yep, this happens to be my tenth year since I signed up here, and it needs to be said that in spite of the innumerable assholic nimrods and great contributors; this site still kicks ass.

ConceptArt.org could be complementary to this site:
I found out about this website from Zanroth three years ago, and it has been a huge benefit when it comes to drawing, painting, and animating. Plus, I think that more people from there ought to consider signing up to here and vice versa. (Examples: Rezeroth, Prometheus/Android Arts, Eugene Arenhaus, Algenpfleger, Asa B, Wiggum/Wendigo, William B. Hand, Robogabo, Sammy Hall, Hideyoshi, Zerdron, Randis, Hanny Honeymoon, Velderia, Pavel Sokov, Original E, etc.)
Aside from myself, here's a list of NG users who also have accounts there:
-Misterho
-Zanroth
-Hyptosis
-Spike Vallentine
-Rockwell12
-Zwickel
-Egoraptor
As an added bonus for this part, here's some related links:

That's all that I have to say...
