Vote change in a Poll

[Journey]

It must be possible to change poll vote if having voted before thinking out answer thoroughly or any other change reason

Hi Journey,

This option is available, but the one who creates the poll has to check the box to activate this option. 

If the poll has been created without the option, it will not be possible to change your vote.  However, the poll creator can return to his poll, choose "Edit poll", and check the box afterward to allow vote change.
