We get bi-weekly bulletins in the mail from my church, and although we can't do everything that the church does, there might be some ideas there. Obviously, we have announcements. You've already mentioned doing that, though. We also have a little report type thing from the youth minister, which just kinda tells what's going on in the youth group and such. (I don't how you'd incorporate that, but...) The preacher also puts in a small devotional type thing. It's like a real short mini-lesson or something. He picks one topic (say patience) and gives a real brief overview of it. That's an idea. There's also a list of birthdays and anniversaries; of course, that would be really hard to do with an internet forum.
Umm...give me a bit more thinking time, and I'll see what I can come up with.
Oh, the new person - the poet - I can't remember the name, but there's an idea. Maybe you could stick one of his poems in there. Poem of the month or something.
There's you a few thoughts to chew on. They're just random ideas, nothing much.
