I would like to suggest a poll. Where and how can I do so?

You can suggest a poll from the home page and the quick poll page. 

To suggest a poll from the home page simply click on the "Suggest a poll" link next to "Discuss" located at the bottom of the quick poll box. 

To suggest a poll from the quick poll page, go to quick poll page and click on the "Suggest a poll" link below the "About quick polls" box at the top of the page. Note: only Professional and Business members can suggest polls.
