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!
I've taken a look at http://www.dot.tk/en/pageA00C3.html and it looks like you need to provide a URL for them to create a .tk address. You can use the free Yola subdomain address that you have and it should work.
