With the rise in popularity of smart phones, more and more people are likely to be accessing this website on mobile devices. Both the iOS and Android platforms have an app called Tapatalk. It's a universal message board viewer. It allows for many different forums to be accessible from one single app, and everything is formatted in the same way. It's really easy to use. I'm sure that there are some people who already use Tapatalk from time to time. I'm pretty sure the simple forum plugin is free, so it shouldn't be much of a hassle to install. I know I'd use it once I get settled into the forums.
