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!
The Yola system doesn't allow direct content addition by external means. People have to be logged into your sitebuilder to do this.
You may be able to do this indirectly by adding a Tumblr blog through the Yola sitebuilder and once that is done users can then add posts into this which will then be displayed in your site through the Tumblr facility.
