The ‘Updates’ page is a true Blog page, in that (by default) it allows the reader to make comments so you can host discussions. You may choose to disable this ability so the Updates page becomes a non-interactive web page, like the others.
Remember that the ‘updates’ page is really just an index page with links to a bunch of subpages, each one designed to host a different topic. You have to turn off ‘comments’ in each post in the Updates page after you write it.
To do so is easy:
1) After you make and save a post, click on the dashboard and select <Posts/ All Posts>
Do this for any posts or pages where you do not want comments active.
