Wasn't there a option that let you change your vote in polls? It's gone now. What happened to it?
Looks like the forum software developers realized that people shouldn't change their mind in polls.
Kind of a shame, as people change their opinions over time sometimes, and it would be nice if we could change our vote on forums to reflect that change of mind should we ever come across old polls again.
Actually, it's now an option. When you create a poll, you can check off a box that'll allow members to change their vote.
You can also set various options such as having the poll automatically close after a set number of days, or hiding the results until that time, even for people who've voted.
