Yesterday, one of the random ideas was about posting blogs and in the comments someone brought up "tags". I didn't know I could do this and wanted to go back to create some. Up to this point I would try to remember certain words and search. This has been fine, but Tags would be better.
I hunted but could find no means of adding tags, so searched the Ideas for that post. Another post about writing a blog came up, so I looked at that. I was hoping for a screen shot that might point out what I was not finding.
Now I am disappointed in what I appear to be missing.
Here is the screen shot of the screen shot.
Here is a screen shot of what I get when I start a blog entry.
I am not sure what is wrong, unless I blocked something.

I looked at the list of blocked items and all I see are the social media icons I custom blocked, since I don't use them and don't like clutter. I checked my cookies and this site is allowed. Our operating system is Linux, (Fedora 20, I think... I don't remember how to find that), and Firefox 40.0.03 is our browser.
Thank you for any help. I wonder if I am just overlooking something. I've been known to do this.
