If so, how? I enjoy posting polls, but most of the time, I really have no idea how to word the question, so I just submit. Sometime within the 15 minute edit restriction, I actually find a better wording, but I could never find out how to change the title. Maybe poll titles can't be edited, so I suppose I just have to think really, really hard in the future. Haha. Oops. Sorry.
I don't think users can, but I believe Moderators can edit them. If you report your main post and provide the details for what you want changed, they should be able to do it. That or you can post a request in the Ask the Staff section.
