Interesting observation. For the record, this was from mobile version. Yesterday, I typed up a reply to a thread and then hit the back arrow and went back to the main forum without posting. I do that a lot. Type out a response and then decide it isn't worth posting. (Yeah I know...with what most of my posts look like....imagine the garbage you don't see). Anyways, I posted throughout the last day and a half in a couple different threads. I just wound up back in the thread I had typed up a reply in. I saw something I wanted to reply to so I hit the reply box....up popped my previously typed up post that I walked away from. Still there, waiting for me to hit submit. Looks like the forum will save your draft should you need to go take a break.
