Currently, this blog can be automatically translated into 13 languages namely:

1. English
2. French
3. Italian
4. German
5. Portuguese
6. Spanish
7. Japanese
8. Korean
9. Chinese
10. Arabic
11. Russian
12. Greek
13. Dutch

The only worry I have is whether the translation is correct or not. And I really hope it will. I can’t really do the checking because I don’t know any of these languages. But should there be any mistakes, you can always blame the translator

You can do the same by adding the Global Translator Plugin which is a free and open source wordpress plugin. However, the plugin ONLY works if your blog is written in English.
