A post is an update consisting of a title and content that you wish to share with your members. You can think of these as similar to the kind of post you may make on a social network like Facebook, or a blog post you may put into Wordpress.
Each post also has an associated date/time of when it was created.
Posts can be accessed via the dedicated navigation bar at the top of your mesh (if enabled), or via post list cards that you can put onto a board.
