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 think you are referring to the Window Title (the name that comes up in the browser tab or window). This can be changed by clicking on the "Properties" sidebar for each page of your site where you want to change this, and typing your desired name into the first box, marked "Window Title." I am attaching a screenshot to show you what I mean.
If you had something different in mind, please let me know.
