Ok, I'm not totally sure what this is all about... but artist Christi Warren, author of the webcomic Diva, very politely asked me to mention it.
Livejournal.com seems to be a collection of online communities and such. Miss Warren runs the Webcomics Community page. I found it a bit hard to navigate, but there is a healthy gathering of webcomic artists there and some fun work to check out. Take a look some time.
