Phorum2phpBB
Finally I did some testing on those scripts and now they should work. You should be able to import all data from any Phorum 3.4.x version but I strongly recommend to first update to 3.4.6.
Both scripts have been tested on an import from Phorum 3.4.6 to phpBB 2.0.6c.
The main update script (phorum2phpbb.php.txt) has been taken from the i18n/Converters forum of phpBB and slightly modified while the user import script (phorum2phpbb_users.php.txt) has been written by myself.

HOWTO:
- backup all data from Phorum
- install phpBB
- set the Phorum database information in phorum2phpbb.php (dbname, dbuser, dbhost, dbpasswd)
- make sure the default table for Phorum is set correctly ($phpbb_forums_table)
- run phorum2phpbb.php inside your phpBB root-directory
- (optional) if you wish to import all registered users from Phorum, edit phorum2phpbb_users.php, set the database information and run it.
