We have recently introduced Tapatalk support here at 2S.
Tapatalk is an app for your Android or iOS device that allows you to browse 2S and many other forums in a mobile friendly interface. It also allows you to send and receive personal message notifications on your phone or tablet.
We hope you find this useful,
Second Sphere Development TeamNB: We have noticed that Tapatalk does not except logins with spaces in the username. Unfortunately this is a problem with the Tapatalk app that we cannot fix.
