For those of you who on the Rules comittee or just someone who wants an opinion, remember that you have the ability to create a poll.

You can add it to a thread already started at any time.

When doing a reply, go into the Advanced editing mode (Go Advanced button)
Then scroll down a bit and you will see something that says Create Poll with a check box.
You check that box and then select the amount of choices. ie. Yes/No = 2
Then when you "submit new thread" you will be able to add those answer choices.

On the poll screen you will see some self explanatory choices, like how long to keep it open and whether or not to show who voted what.

Pretty easy and can take up less space and effort then having to reply with a yes or no.
