Tapatalk asks mobile users (or tablet users) to use it EVERY single time you open a forum website, even when you don't want to use it. I prefer the desktop version of forums on my tablet. But Tapatalk doesn't remember that I've said "NO" - it still asks EVERY single time. Annoying.
that can be disabled by removing the javascript part though when setting up, so it never prompts, but is available for those that want it.
