Does this forum allow the ability to change your vote in polls? I don't see an option to but was wondering if it was something that could be tweaked to allow it.

For example, I see polls with titles such as "Have you cracked your screen yet?" or something similar. If you vote "no" and then 2 days later crack your screen, it would seem reasonable to go back and change your vote to "yes."

There are other forums set up that allow this so I was just curious if it was an option here.

Thanks!
