I'm on my first cuppa coffee and not quite awake yet. I didn't read all the comments yet, but I appreciate everyone's help.
All of my categories weren't showing in the sidebar after all. I had one category as a sub-category. When I removed it as a sub-category and posted it just as a category they all showed up in the sidebar.
My Kaboodle blog isn't commercial. It's just a compilation of sites I'm interested in - mostly shopping, but yes, I'll update my profile. Listing my WordPress blog makes better sense. I didn't realize it doesn't automatically show up with my profile.
Thank you for the reminder about advertising. I do have some links for shopping at my Half.com store, as well as referral links for search sites like Blingo and Winzy. So those aren't allowed?
Thank you for all your help drmike and timethief. I'm not too familiar with the WordPress documentation yet. I didn't know what to look for in the .css for categories that would let me know they aren't or aren't included in the individual post. It looks like I have lots and lots of reading to do.
