ClassTag is an interesting new site that I just found out about from Free Technology 4 Teachers. ClassTag allows educators to create a class directory and schedule appointments w/ parents. The way this works is by integrating a calendar feature where educators can create "slots" where parents can then sign-up. This helps avoid people get signed up for the same time and avoid the use of paper/handouts. Also, this is a great way to share announcements w/ parents to help remind them of upcoming events.
I highly recommend checking out ClassTag by clicking here!!!
