The webform plugin offers one to create forms for their website.

Many plugins offer webforms to enter their settings and other data. Similar forms can be used to ask end users to enter various information, such as a contact page or a "Notes" sticker for a user to let us know of a problem on a page.

The webform plugin has an interface to let website administrators create their own forms. The forms can be saved in place, the content sent via email, or accumulated in a list online...

This feature will also include statistic gathering (i.e. votes such as +1 or -1 or 1 to 5 stars as seen on various websites.)
