Hi Sue,

Great questions! These two options were both referring to features available in Totara Engage, which was part of our Totara 13 release. There are a range of resources about Totara Engage on the Community, but you might start with our short explainer video or product sheet for a quick overview.

We actually use Totara Engage in the Community, so you can also get first hand experience of these features by going to Your Library. Here you can create, share and save resources and playlists. You can also share, like and comment on resources in the catalogue. I've just shared a social learning playlist with you to get you started. 

Any further questions don't hesitate to ask!
