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!
You are certainly welcome to add chat rooms or discussion boxes to your Yola site, however, you will not be able to make the next Facebook.
Facebook is a massive social networking facility with major resources in terms of technical staff, servers and funding. Yola's resources are dedicated to helping people to have their own websites - which is a slightly different service.
You can read about adding a comments box here and chatrooms here. Good Luck!
