Hello, I think the wordpress should have already installed "translate content" plugin. Nowadays people create blogs/websites which are targeted at international groups. To present it self better, a company that makes their website using wordpress.com must have their website on at least two different languages depending on what sector they are working with.
I my case, my customer wants his website translated to four more languages and I have trouble finding and installing a plugin that would fit the webdesign.
I hope my feedback was helpful for you. :)
The blog I need help with is cafemeza.dk.
