Some other quick tidbits....
'Editted By' is not added to a post til 5 minutes has passed, so you can dit your post without that message appearing just to fix simple mistakes. At least, that is how it is setup, I have not tried it myself.
If enabled, you most likely want ot disable this setting in the User CP. Mine was disabled when I started testing, so it is odd it is enabled on so many. And, no, I have not seen a way to glabally disable it (yet).
USER CP --> Edit Options -->
Use 'Email Notification' by default?
Using this option emails you whenever someone replies to a thread that you have participated in.
Set to no.
As for post counts, I'm starting to think UBB must have counted PM's as posts whenever the the site needed re-indexing.
In the move, besides losing PM's and Everything Else, we only lost 5 threads from the War Room, and 1 thread in International.
Much better than the usual UBB upgrade (Except for the PMs and forum, but we have an archive of them so...) where we would lose, on average, 60 or 70 threads, mostly in the war room, or because the thread became too big for UBB to handle.
Need sleep......
