A few months back I saw some threads with a poll built into them. I'm trying to post a poll. Does anyone know how to do this? I can't seem to figure it out. Is the option no longer available?

As far as I can tell only Zup can make a poll.

You could try something like making a thread with the question then make a "yes" post and a "no" post and ask people to respond by pressing "thank you" on their choice...
