Welcome to SSP!

(Approximate onboarding time: 45 minutes -- see time breakdowns next to each video)

These videos will introduce you to some of the tools you need to successfully start and navigate through this course. The recordings are from a live demonstration during a previous round of SSP, and may refer to it by number, but do not worry! These instructions are still relevant to you and your current SSP. Please ignore any referenced to the SSP numbered 38. I'll say it again..

>> Please ignore any references to the SSP numbered 38 :-)

Now that we've got that out of the way, let's get into the videos.
