Have you ever tried to post a wordy poll, only to get a call right before you hit send, so you answer the phone, hang up, then start to rewrite your poll, not realizing it's already been posted?
You can close one of them.
Ha! I wondered what happened!
I have had it happen that I'm committing a lengthy one and go to post and a notification comes up and it brings me there and I lose the comment. That makes me wanna throw my phone...
