Primetimer's forums are fully usable from mobile devices. On mobile devices, the navigation is a bit different, and many features are accessed from so-called "Hamburger Menus" - 3 horizontal lines indicating a menu. 

When clicked, the menu icon on the right-and side will open a panel allowing the user access to more items, like their inbox and notifications.

If you experience any issues with the mobile version of the site, please let us know in the Bugs area, and make sure to mention you're using the mobile version, and what type of phone or tablet you're using.
