Currently, it is impossible to change your vote in any poll on Manifold. This seems like a good feature to have, since users might change their mind, or just vote for an option accidentally.

Resolves YES if, at any point before December, it is possible to change your vote on at least some polls on Manifold (even if this is, say, a feature that the creator can choose to allow on their poll or not, or if it is only implemented for new polls). It doesn't count if it is an experimental feature that can only be used by Manifold employees - non-employees must have access to it, at least.
