I created several blogs using WordPress. First, it was just for fun, I had a blog to talk about my life. But it became professional, and now I'm using WordPress on several websites, such as vivelepcf.fr
Every time I need to work on a WP theme, I'm glad the WP Codex exists, because it is a great help for me. Now I wish I'll be able to contribute to the Codex, with a few French translations.
You can contact me through the Codex, on this page.
