Please consider setting up a mobile skin so users could view bitcointalk better from a mobile browser.
I’ve tested almost every single mobile view kinda extension for the forum out there and personally I still find the regular look better than them though. On android I prefer the desktop view on iOS the normal view seems ok and sometimes depending on the browser you get little mod aesthetically.
Search mobile extension here or on talksearch and test as may as you find till you get the best fit for you. I’m not sure those two here are the only ones.
