We use TapaTalk on Socially Uncensored and to my surprise I found that Google Chrome support has been added. I can now use it even without a mobile phone.
It would be cool to see it added here, but I would assume that XenForo has no plan on it. They want to keep it on a stock install, which is understandable. And in the future there "maybe" a mobile skin or app, which I doubt adding Tapatalk would help promote.
