Adding a Like button
So.. I'm building a course for students and was thinking it'd be great if they could hit a "Like" button at the end of the course if they liked it. Is there a way I could potentially collect that data? I'll have basic LMS tracking, so I don't need any more details about the user other than the number of times that button was pressed...I'm hoping something like that is already around, or somebody can help me with what functionality I can use in this new way? Pretty please? Thanks!
