Wow, the light has dawned; the road is clear. I just figured out the difference between tags and categories. I thought I knew before because I’ve read the “help” page on it several times. But no!
So from now on, I’ll add tags (as well as my already established categories) to my posts and see what happens. In other words, I will add more specific words in the Tags Module box of my post!
Learning the blogging process is truly a fun learning curve for the novice. And I agree with many people on the forums that WordPress information on every topic is really, really helpful.
