Dear Richard. Have you tried clicking "My Account" at the top of the page and looking at the "Statistics" menu down the left side of the page? You will find a listing of all your Hubpages. Alternatively, you can click, "My Profile" at the top of the screen and this also takes you to a categorical type listing of your Hubs, Favorite Topics and Hubtivity. Give it a try.
Oh, Richard. You know what? I tried to use the search engine by pasting in the title of your Hubpages and also found that your Hubpages did not show up. You have a very good question to ask the Hubpages Team.
Okay. I used the advanced search and was able to find one of your hubs using this tool when I entered "nissan sentra consumer review" Let me know if that works. But, also I would ask the team why it doesn't show up for the regular HP search engine.
