Polls are only able to be posted by maintainers of the community and, strangely, anyone else who has a paid account. If you would like to be a maintainer, this can be arranged, although such status would be revoked for abuse.
Bribery is a guarantee of becoming a maintainer - give the gift of a year of paid membership for the community and you're a shoo-in. I only say this because there are no jerks in our community. Yet.
