Remind101 is a service that provides a safe way for instructors to text message or email students. Using Remind101, instructors can engage their students more effectively without needing to know their phone number and without having to give their phone number out. This is currently a free service. Instructors can have a separate "number" for each course. For more information go to the Remin101 knowledgebase. There is also a video on YouTube that shows how to get started at: http://www.youtube.com/watch?v=gME_zwLeRV8. Remind101 is at https://www.remind101.com.
