It took quite a bit of time to translate and organize Kyle Eslick's selection of WordPress themes, but I'm not sure exactly how long it lasted. Nine articles in total, actually not much content, but I am a bit lazy - always procrastinating, and finally finished today.
This series of articles can be said to cover all types of WordPress themes. They may not be considered classics, as many people are collecting and organizing themes, but Kyle Eslick's series is the most comprehensive one I've seen. I would also like to thank Mr. Kyle Eslick for his hard work here!
