Allowing Members to Freely Remove/Edit Polls

[That One Guy]

Hi everyone.

I've been searching around the modifications for vBulletin 4.2.x and also around this board but I cannot seem to find a solution and/or answer to my question.

In SMF, Users were freely able to edit and/or remove polls as long as they were the owner of that thread.

For vBulletin 4.2.2, I know that Mods and Admins can remove and edit the polling. However, we do not want to overburden our current staff nor do we want to increase our current size.
I also fear that our current users may become very disgruntled having to report to Mods to keep on deleting their polls so they can try to make more for weekly tv show discussions or weekly random polling.

Are there any confirmed paid and/or unpaid modifications that are working when it comes to allowing regular members to edit or remove their polls (as long as they started the thread)?

Thank you for reading!

Edit: Also, I have another question. Can polls be made in the same thread once it is deleted? I haven't tried because I'm still too busy with setting up the website
