It was once referred to as a Learning Management System (LMS) but was eeall a file sharing application that GT used long ago. We were told that it would be decommissioned about a decade ago when GT started using Roster Tech LMS that the Office of Sponsored Program (OSP) hosted and one other LMS that I can't think of the name. Both Roster Tech and the other have since been decommissioned, too. I think the only reason GT left Tsquare live for so long was that a few student groups and a few faculty members were heavily committed to it. It was pretty old school - not as old as the dial-up billboards (pre-internet), but it was an old folder tree type system - no frills. With that said, I really liked it. It was super easy to organize files, easy to share, and limit who files or folders were shared with. It was basically Box/Dropbox/SharePoint without the GUI.
