I've just updated the Tapatalk module for the forum, and it appears to have quite a few improvements since the last time I updated it (earlier this year).
Tapatalk is a mobile app for interacting with forums. Since it only transmits data and not whole web pages, it is a very fast means of browsing / posting, even on relatively slow networks. I'm actually using it now. There are versions for the iPhone, iPad, Android, Kindle Fire and other mobile operating systems.
There's even attachment support, which is quite nice since you can't upload photos normally when using Safari in iOS. I just uploaded the above image from my phone's photo library as a test.
I definitely suggest checking Tapatalk out if you browse the forum from a mobile device on a regular basis!
