Unless there's a way to shut off that automated "Sent from my X using Tapatalk" message that sounds like you're being mind-controlled by it, there's no way I'd use it. I usually only post small and easy message from my phone or tablet anyway. I do all the big stuff on my desktop.

Trying to use BB code with a phone's default keyboard is really pesky. I usually don't do that unless I really need to.
