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!
If you haven't built your other websites with Yola, I'm afraid it won't be possible because of compatibility problems. You will need to rebuild your websites using the Yola Sitebuilder. I'm sorry I don't have better news for you.
