BlogSelect is designed to allow you to "Connect" two or more TotalCms Blogs via a "parent/child" relationship. A Blog post in the "Parent" Blog Post uses a field to store the permalink of the "Child" Blog Post.
In the admin area of the "Parent" blog form BlogSelect provides a dropdown list of all blog posts in the "Child" blog. Making a selection Connects the two blog posts. This is a very powerful tool with many uses.
