I have implemented the new vBulletin mobile system for APUG. This is not a 3rd party app or hack, it's an official vBulletin product that ties directly into our forum. It requires nothing on your part other than a mobile device with a web browser. Simply point your phone or tablet to http://www.apug.org and it does the rest. It will auto-detect you device and load the mobile APUG site. So far it looks great and seems to work well, probably the best mobile system we've had yet. I would appreciate any feedback on it as I can only test it on Android.
