If you need support from Yola please contact us via email@example.com 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!
Google had this facility of comparative testing for versions published in webmaster. I really don't recall the details and I am unaware of it still being offered. It was free and it was open so you may like to do a search in webmaster?
