If you need support from Yola please contact us via firstname.lastname@example.org or make use of our live chat service! We are working on a new approach to community-based support and during this transition period we are not adding any new threads to this forum. Many thanks to everyone who has participated over the years and we look forward to unveiling a new peer-to-peer support system soon!
There are a number of ways to create a site with more than one language. As you mention the use of sub-domains linked to each other, the use of navigation to take you to one language or another, or by the use of anchors which would take you either to one language or the other on the same page but the content separated so as not to see both languages at once.
