Making your own poll is easy. Just put a question in the title, fill in some options and click save :)
If you're going to post somewhere with a dark background the text may not be visible for the poll options, so un-check the transparent background and it'll have a nice white background for you.
You can set the amount of time each user has to wait between voting, from 0-9999 minutes to help stop vote rigging. You can also require people to be registered and signed in to b3ta.com before voting to stop vote rigging (Though this option should only be used if the poll is going to be posted on b3ta.com)
When you're done, click Save to generate the poll and get the HTML you use to post it wherever you like.
