It has come to my knowledge that wp-polls and wp-postratings does not work with Opera. After much research, I found out that Opera does not support alpha/opacity.

» WP-PostRatings Fixed postratings-js.js
Just overwrite the old .js file with the new .js file as attached in the forum post listed above.
How about adding an option allowing the site admin to choose between logging votes by cookie or ip (or both, or neither)?
Most of my readers are behind NAT routers, which means that currently only one user can vote because the IP is logged as having voted.
Yeap, this feature is already in WP-Polls 2.1
Thanks for fixing it.
