Thanks, Alex.

I've run the script, and it's failing silently.

[tfinney tools]$ ./import.pl --append-data --add-bad-email --forum-id=2 --debug --logfile=/www/logs/gforum_import.log --type=WWWBoard --source=/www/htdocs/wwwboard/water/

Import completed successfully.

I had to tweak the regular expressions in Import::WWWBoard to get the fields to populate, but that's not rocket science (famous last words, eh?). Looking at the database, I see that the posts are being inserted into gforum_Posts. However, none of them are shown on the forum's index page.

If you have any insight regarding where to start with this, I'd appreciate it.
