Hi,
Here's my scenario. We've got an existing PHP-enabled Web site. The powers-that-be want to set up a user log-in/password on the front page, so that users can log in once and get access to downloadables (white papers, demos, products) across the site. Ideally, we would store data about what each user downloaded while on the site.
I'm looking for a system that we can implement on this existing site that will address this user login/tracking issue. We're not picky--we'll take open source or we'll pay for it. I welcome all suggestions and recommendations. Cheers. DB.
