Hi John, A friend of mine uses a forum provided by http://www.phpbb.com/, II find it a very useful, powerful and customisable forum, with excellent security (Geez starting to sound like a sales pitch! ;) ), if you'd like to see it in action have a look at: http://www.civictype-r.co.uk/phpBB2/index.php or http://members.lycos.co.uk/tidaladvection/index.php, it's free to download but does require setting up, which from the sound of things won't bother you in the slightest!
