So it sounds like it wouldn't be as simple as pointing it at the new DSN... Argh! What to do... what to do?

Being a textpattern and Basecamp user, I would also vastly prefer Textile. I even use it in my own web applications for markup entry and had to create an ASP class to support it since textile support is missing from VB Script Active Server Pages.

I'm evaluating PunBB as a forum solution for my company and like what I see regarding XHTML/CSS support and a broad feature set.

Unfortunately for me, we're running IIS on Windows machines. Both of my load-balanced web servers already use Microsoft SQL Server as the back-end database for our custom web CMS, so I'd like to use that DB as well for PunBB.

Does anyone know what it would take to use my existing Microsoft SQL servers instead of MySQL?
