I've been considering doing this myself. My iPad is just a giant iPhone it's really no better. I kind of miss having a mouse and a keyboard, plus uploading pictures on an iPad/iPhone is a pita without tapatalk.
There is a few threads on this, the forum admins are aware of the problem, unfortunately I think advertising is at the top of there priority list
I use tapatalk for a few other forums, they all work 100%. There is another forum for planted tanks that works well for planted tanks. Its no tpt, but I have been seeing a lot more tpt members "make the switch" since this tapAtalk issue started.
