Our county has an in-service in August for which I have organized ten groups to do presentations. If you come to this site in August I will be putting all of those in-services and their "handouts" on this blog. One of the sites we will discuss is Remind101 which has been one of my favorites for years. I use it to communicate with students and parents about what they should be doing at home. This year I have also used it on days when I cannot be in class. So recently I was grading AP exams and I pre-set a message to my class so they would know their assignment. Since you can use Tinyurl to shorten the link address and then you can send it to your students in class when you are not there.
