I used to use Tapatalk to browse on my cell phone but I had to quit using it due to there being no distinction between what was quoted from a previous post and the new post. I know that it's not a Tapatalk issue as I browse other forums on there and don't have the same issue with them.
I also second (third, fourth... etc??) needing a way to get to the last page of a thread on a mobile device.
