I installed a new feature on the system today that improves the look for mobile devices. It is still in development, but if you access the forums with your phone, etc, you might want to try it. No app needed!
Once logged into the forums, go to the lower left hand corner and change the style dropdrown from SuperCub.Org to SuperCub.Org mobile.
You can do this from a regular browser too, not as robust as the full version, but easier to read on a phone, etc.
