The latest content that was posted through NNTP to forums.macromedia.com is missing. My last message was posted to macromedia.coldfusion.server_administration at Sat, 04 Apr 2009 10:34:54 +0200, I don't know who else has posted all through the weekend. (The NNTP interface was enabled until late Saturday.)
Now I'm confused by your post. Didn't they announce that NNTP would no longer be supported?
He's no doubt talking about NNTP to/from the old system.
NNTP is no longer supported. But all messages that were posted to the old NNTP system were supposed to have been imported here.
They may have cut them off as the time the forums closed (3:00 Pacific time) even if the system still seemed to accept them. Depends maybe on what time that part of the database was imported.
