As a member of Classlist, there are a number of different ways you can use to communicate with other parents.
1. You can post to parents in your 'Class' or 'Year' by posting in the relevant groups, either on the Home page or on the Groups page. This means that everyone in these groups can see this post.
2. You can communicate to parents in your class or year, or any other parent at your school via the private messages function (accessed from the speech bubble by your profile picture), allowing you to choose specifically who receives your message. However, to message parents not in your year group, both the sender and receiver must have opted in for the School Run feature.
