I've just enabled the polls option for everybody. Now you can create a poll by going into a sub and clicking the Submit a poll button below the regular post submission buttons.
Sub owners have to opt-in to allow polls in their subs, by going into the sub settings and ticking a box. For now I've enabled it on /s/Whatever.
Soon to come:
Scheduling when a poll will automatically close(done!).- Voting for more than one option
- Adding an option on poll creation to show who voted for each option
Polsaker, it appears that polls aren't available on mobile.. or, to quote my wife, am I doing it wrong?
