When we move the database from here to the new server, it will replace everything there. So any posts you make before the move will be lost, any posts after will be permanent.
Any posts you make here before the backup will be preserved, any posts here after the backup will be lost.
Bottom line: Post here until the backup happens. Keep posting here after the backup is announced, with the knowledge that these posts will be lost. Copy any posts you consider important to your hard drive, and repost them at the new place when the move is complete.
I just read the PHPBBer TOS. Can someone point out to me where the problem section is?
The TOS itself is straightforward. But someone in another thread linked to a discussion on the phpbber support forum, which seemed to indicate that "inappropriate content" is subject to a wide range of interpretation.
