Well, ok, there's status updates, but that lacks the persistence & length possibilities that announcements had. Blog posting sound reasonable - except that it doesn't appear to be enabled (which makes sense). Even with blog posts, they would lack the positioning of announcements.
There's also the issue of _prior_ announcements and files - they didn't make the transition. Which again is understandable, but the stuff is just _gone_ - no warning.
Not a really big deal in my own case, and these were probably under-utilized features in the first place. I'm assuming that was checked.
As for previous forum posts, my older ones are still associated with my user id, but some of the more recent ones are not. It appears that a snapshot of the database was taken at some point before the transition, and then work began on that. Those recent posts _are_ still in the forums, but the association with user accounts doesn't seem to have made the transition.
This would seem to have a much greater impact than the user profile changes.
Links: those are pretty much destroyed across the board. The url structures in the forums appear to have changed in more than just the root, with even the post and thread id's different.
Is there a mapping for those ? As in, old = new ? So that maybe a 404 page (or some other approach) can be created that can recognize an old url and redirect to the new one ? Just a thought.
