Once set up, you can send a text message from the Remind 101 website or from an app on your phone and that message will go out to anyone who has signed up for your service. The whole process is pretty simple. First go to the https://www.remind101.com/ site and create an account. When you create your account, you will want to use your real name as the messages will be sent out using that name. Next you will be asked to name your first class.
