Hello. We do still have some artists in the group Scribblers' Den but we're mostly writers. I also recognize a name, or two, in the members list here from the old SPE, but I have no idea if they're currently active. Me? Sorry, but I have a hard time drawing a straight line with a straightedge. If there isn't an artist's group here, you might start one yourself, if you're feeling ambitious.
Ah, so they've taken refuge with the writers. I might look into starting a Doodler's Den, but maybe sometime later if the site grows a bit.
By the term "visual artists" are you referring only to those who create 2D art such as painters and cartoonists?
