I’m looking to integrate PHPMotion (a video CMS, youtube clone) and my phpBB3 forum. Both have been recently installed/uploaded with no real users signed up to either application. I only want one registration page and one login page for both the forum and video site. When a user is deleted from either the forum or phpmotion, I want that user to be deleted from the other part of the website. Note well, I only want login integration; I don’t want private messages or profile pages integrated. I want the hacking involved to be as minimal as possible so when updates come out for PHPmotion and PHPBB3, I won't have to go through much work and can do easy upgrades.
