I've taken over an Office 365 admin role (using SharePoint Online 2013 in particular here) and we're in the middle of a data migration. I was asked to look into displaying a Terms and Conditions page for users logging in after a change.
After some research it seems the best recommended course of action is to create a User property and set to false and create a User control on a page to check the property and if false, redirect to the Ts&Cs page and once accepted change to true for user.
However I haven't done much more than assign user permissions through AD security groups in SharePoint and have a feeling this is far and away more advanced.
Does anyone have a Technet article or tutorial to show me where to begin with this, a lot of what I'm reading says I should be very comfortable with building and deploying Web Parts via SharePoint (spoiler, I'm not).
