As a learner, you may be enrolled involved with multiple institutions that use Riipen and thus may be a member of many portals. While Riipen supports users being a member of an unlimited number of portals, you can only have one active in your navigation at a time. This active portal is your current "workspace".
Click on your user avatar in the top navigation bar and select "Switch workspace".
Select the portal you would like to switch to
When you switch your active portal, you will be redirected to that portal's subdomain, and what you see throughout Riipen will then be filtered to that selected portal including the content you see in your dashboard and the options in your main navigation.
