Has anyone used OLC / Alerts to manage Spaced Learning?

Summary:

Has any used OLC and the alerts to managed spaced learning?

Content (required):

There is quite a bit of evidence that spaced learning helps with knowledge retention and I would love to try it out with some of our compliance courses. The idea would be to send a series of 4 emails at weekly intervals after someone has completed the initial e-learning. Each email would contain one key point from the course.

Has anyone tried anything like this? How did you do it and did it work well?

I'm assuming we could do using alerts?
