And, maybe just leave it that way? When vBulletin introduced the really great Notices functionality, I stopped using the dedicated Announcement functionality. I only posted 'Announcements' by hand in our Announcements forum, but for forum-specific 'Announcements' I started using the Notices system. Those were/are much more visible to the enduser compared to generated Announcements. And they are more flexible. So, please everbody, support this suggestion:
