Enable WallForum on your wiki and highlight a thread containing your message. Simple. I can tell you from direct experience that it's far more effective at grabbing people's attnetion than Community-corner.

Both methods suck in one way, though: neither alerts IP editors in the way that MediaWiki:Sitenotice does for Monobook users.
