It's Lawrence here from Aborior. We've recently released our new forum package that is ideal for creating a powerful message board, or for web hosts to created networked message boards.
It's a highly customisable and versatile forum package, featuring a template based system for true 100% customisation. Other features include forum networking, integrated message management, full e-mail notification, cookie saving and a slick user and admin interface. Of course, those are just a few, with a lot more available.
Anyway, I won't go on too much more, other than to point you to http://www.aborior.com/products/encore, where you can find all the information you need, and download a FREE trial. If you have any further questions, feel free to drop me an e-mail or post in our own community forum (or here if you prefer).
