I've installed Tapatalk to our Forum. If you want to use it you need to (probably) pay for and download the app. Pointers to apps for various devices can be found here: http://tapatalk.com/mobile.php. Once int he app, search for us by forum name. See the Tapatalk site for info on the apps.
Post your experiences here. I logged in with my iPhone & iPad and it looked like it was working as advertised.
Please note: We do not support the user applications, only the Forum server side of this. See the Tapatalk link above if you need app support.
