* phpbb2 forums port version 2.1 (c) 2003 - Nuke Cops (http://nukecops.com)
*
* Ported by Paul Laudanski (Zhen-Xjell) to phpbb2 standalone 2.0.4. Test
* and debugging completed by the Elite Nukers at Nuke Cops: ArtificialIntel,
* Chatserv, MikeM, sixonetonoffun, Zhen-Xjell. Thanks to some heavy debug
* work by AI in Nuke 6.5.
*
* You run this package at your sole risk. Nuke Cops and affiliates cannot
* be held liable if anything goes wrong. You are advised to test this
* package on a development system. Backup everything before implementing
* in a production environment. If something goes wrong, you can always
* backout and restore your backups.
*
* Installing and running this also means you agree to the terms of the AUP
* found at Nuke Cops.
*
* This is version 2.1 of the phpbb2 forum port for PHP-Nuke. Work is based
* on Tom Nitzschner's forum port version 2.0.6. Tom's 2.0.6 port was based
* on the phpbb2 standalone version 2.0.3. Our version 2.1 from Nuke Cops is
* now reflecting phpbb2 standalone 2.0.4 that fixes some major SQL
* injection exploits.
