There are a lot of options for Posts. For example, currently the system is set to only show an “Excerpt” of the full Post on the Our Blog page with a “Continue Reading” link for each Post. The Excerpt can be the first portion of the Post, or something entirely different.
We can allow folks to add “Comments” to Posts, currently turned off. If on, we can allow anyone to comment, or only logged in Users. If Users are allowed to Comment, then we need to turn on the part of the system that allows folks to create an account. This is built into the system and all we need to do is turn it on.
