This is probably good to be considered for any types of votes, but I'm especially asking about the close vote because of the special significance they have over the usual up/down voting.
This was brought to mind by a particular post: Is it practical to run a weekly lunch-hour game of D&D with my coworkers?
The original wording of the thread was something along the lines of "Is it a good idea to...". I voted to close because the question's wording made it too susceptible to being subjective/argumentative. I also made a point to (as I've suggested in another thread) comment on the post, to address the reason for my close vote.
However, the OP has since changed the title and content of his question to be a bit more agreeable. Though it seems the question will not likely get voted closed, I'd like to have an option to un-do my own close votes for this and similar cases which might otherwise end up closed.
Can this be done?
