I finally took the bullet and moved the articles from the personal site hosted by my ISP to Hobbytronix.net. I will have to check all the articles again do whatever improvements need to be done.
I also wrote some articles for the Travel and Gardening categories.
In WordPress, I added some more plugins. One of them handles nicely the Google Adsense and that made my work a breeze. Another one is a tool that allows modifying easily the colors of the website. Another one handles Google Analytics.
