So a brief post on this because I have wasted too much time already. When v 2.5(?) of WordPress came out they put in a means to “tag” posts. Now, if I understand this correctly and that is a very big “if,” tags will help your posts be searched through the intertubes. Poking around I found that there is an “import” feature allowing you to convert your categories to tags. NB – It destroys your categories! So they are all gone and I am left with 1,300+ posts with no categories! They all have their tags, but they don’t show up with the post, they are however tagged. The “cloud” on the left is now a “tag cloud” so if you want to find, say, my posts with or about comics simply click on that tag.
*sigh* not intuitive at all.
