Online Training and User Tracking

Hello everyone, I want to build an online training center that let's me monitor/track user progress, througout an online curriculum. The goal of the project is to be able to 'certify' the user after completing certain lessons. I want to: -have online exams,etc. -make it possible to track each user's progress -provide online training videos -provide access to reference documents [searchable db], etc. I'm looking for recommendations on the best tools to use to create and manage, such a system. I'm currently looking at MM COURSEBUILDER, combine with NT+SQLServer+PHP. I wanted to know if there is better way to approach this. 1) Have any of you done something similar? 2) What software do you recommend for this? 3) I plan to use NT+SQLserver+PHP and/or else. Any suggestions, comments? What are the best tools to do this? By 'best', I mean: -easy (relatively) to implement -easy to manage [template based] -scalable Any help would be greatly appreciated. Thx in advance! -John __________John Monfort_________________ _+-----------------------------------+_ P E P I E D E S I G N S www.pepiedesigns.com "The world is waiting, are you ready?" -+___________________________________+-
