One of my client wants to develop a training for an audience outside the company. The training should be available via internet, but it should be possible to track completion in some way. I know there are different LMS systems out there that you can use via internet/cloud. Does anyone have good experiences with one of these? The system should be absolutely trustworthy, possibly SCORM compliant, easy (and free!) to use for the enduser. Budget is not an issue, my client is willing to pay a fee.
