Ok everyone, please give it another try. It should be working in all forums, on all mobile devices now. If it still doesn't work for you, please let me know the make and model of your device, and browser (if applicable).
Thanks for your help, and a special thanks to
dartho, the developer of the mobile detection plug-in we're using, for helping get this working properly.
One final request: If you could, please upload a screenshot or photo of your mobile viewing the BigBlueBall forums. I'd like to see what it looks like on a wide range of devices.
