I have translated the website bludit.com and all its sections into Russian. This is the official site of free and open-source CMS Bludit (my site powered by this CMS, just check the footer). I also modified the translation of the CMS itself, translated all the plugins and themes. For me it was an interesting experience, I met the developers, they are great guys. You can always see the results of my translations by opening the official website bludit.com or installing this CMS.
