how do i delete a polle

Read link.

It's a bit of a mystery, but users can't delete picks. I understand why users can't edit their picks - it would be too much opportunity for abuse to allow someone to write a question "Do you like sunshine?" with "yes" and "no" answers, then, after dozens of people had answered, then change the question to "Do you wet the bed?" or something similar. But deleting the picks?

My guess is that we don't have that ability in order to prevent a lot of picks going up, users taking the time to answer them, and then having the person who posted the pick decide to delete it on a whim (or because they didn't like someone's comment). It should encourage us to make sure to get the question and answers correct the first time. I feel for you, though: I just asked a question I wanted to edit or delete yesterday (I'd meant to specify the question to men, but didn't notice that I hadn't until just after I'd posted it).

In any case, regardless of the why, we can't edit or delete picks. Hopefully that's what you meant by "polle."
