How to make? Most forums are like software. You simply upload the files (install) it to your server, run the install.php file and then all your pages are already created. The only thing you can do is custom the template to the color and theme you like, but most themes are already created for you and you simply need to just run their install to get your site looking the way you want. Go to
www.phpbb.com and get your free forum and also go to
www.phpbbhacks.com for cool features and theme templates. Good luck.
If you still find this difficult to do on your own, you can hire a forum installer

FrontPage can be useful at a later time, if you wish to use that program to do minor editing of your forum.
