help with community blogging!

so i turned my other livejournal, “artsflow” (username: ) into a community blog, so that other people could post arts announcements, and now i can’t post to it! i can’t figure out if i (bodega) or i (memewatcher) should be doing the admin but neither seems to have permission to add users or anything at the admin console. i’m sure i’m doing some basic thing wrong.
can anyone tell me what the next step is so i can post to artsflow again?
