New from SitePoint, there is an interview with an author/coder on one of the larger forum systems written in PHP.

With the looming Gold release of vBulletin 3.0, I was pleased recently to have the opportunity to interview Kier Darby, Lead Developer and Product Manager for vBulletin at Jelsoft, the famous UK-based firm that develops the well-known forum system.

They go through the usual questions - more about him, history of vBulletin, coding preferences, etc. They do cover one of the more infamous items about vBulletin - the fact that you must buy a license to use it. Their answer?

Charging customers for a vBulletin license means that Jelsoft can afford to pay a very reasonable rate to both the development team and the support team. It adds greatly to the stability of a product or a company if its employees have a degree of loyalty to it, and if those employees have been working with the company and its products for an extended period of time.
