Need app suggestions ...

I am going to set up an application for faculty at my school to post assignments. The same app will probably be used for club advisors to post announcements and whatnot.

My current idea is to use a forum of some kind, but I'm not sure which one will work best. Ideally, I could include individual forums or threads from the bbs onto other pages of the site. What I mean by this is that it would be nice if the English department page could include just the English teachers' forums integrated into standard html/php pages.

Any ideas? Is there a php forum app that is already set up for this? Should I give up on the integration idea and just run the app with a header and footer, and link to certain threads from other parts of the site using standard hyperlinks?

I look forward to your ideas.

There's lots of ways to handle your app.
I wonder whether phpBB wouldn't be an adequate solution at leats to get up and running. And best parts - free and easy.

Set up a separate forum for each department. Create a sticky pages in each forum containing static schedules, etc. Then let forum moderators update the stickies as needed.

here's the phpBB link --- http://www.phpbb.com/
