Multilanguage site with two domains

I recently answered a very similar question.

Instead of having 2 separate websites, it’s far easier to install a translation plugin. The plugin will basically add extra fields or tabs in edit mode. For example, if you are editing a page titled “Home”, you will have a field for the English page title and then a field for the Spanish page title. The same goes for the description field.

Configuration is very easy and once you’ve selected the languages you need, the plugin will automatically add these fields to edit mode.

There are 2 very good WordPress translation plugins that I use on a regular basis.

WPML (http://wpml.org) is my favourite. The only downside is that you have to pay a yearly license. If you’re looking for a free plugin, check out: QTranslate.

Both plugins allow you to have sub domains (en.yoursite.com) or language folders (yoursite.com/en).

Best of luck!
