Usually I posted previews and other comics-related stuff on newly_legion community. But recently the community rules have changed, and now all posts there have to pass moderation.
I don't know if it's the owner's decision or LJ's new rule - but, to avoid waiting for moderation, I created a new comm, buffycomics. So far, I posted preview for Buffy #2 there. More stuff coming soon.
The community is open to everybody and members can post there without moderation.
To see friend-locked posts, you must be a member of the community.
