Hi there, I'm really proud of where I've gotten my website so far and have taught myself all of the scripting and template design for my movable type-based site. However I want to add a section where users can register, log in, and save articles (from elsewhere on the site) as favorites. I don't even know how to go about finding tutorials to do this. Does anyone have any suggestions for systems that would work well for this type of expansion? Any advice would be really greatly appreciated!
