There isn't any official bukkit version for mobile. This site was made by volunteers and it would take quite a bit of volunteer work to make it for mobile also
It's Xenforo, I guess you could use TapaTalk if TnT or EvilSeph added a Xenforo plugin to do so. http://xenforo.com/community/resour...enforo-ios-android-blackberry-mobile-app.263/ I agree, having a mobile site would be advantageous.
