Encourage your users by letting them express their feelings by "emoting" rather than voting.
This is possible using WordPress built-in custom fields. Add a field with the name
emo-vote and choose value.
The value can be unique for each post.
How about upgrading your browser? Just kidding, some unlucky ones are still stuck with IE6.
I would recommend TwinHelix's PNGFix.
blank.gif files in your webroot and add
behavior: url(/iepngfix.htc); to the #input_0-#input_4 elements
Some might experience a lack of callback after emoting. In other words, the new values aren't sent back as they should.
The callback is using the PHP function
in PHP 5.2. Check your current installed version of PHP and ask your host kindly to upgrade if you're using an older version than 5.2.
The info shown in the widget is begin cached for 15 minutes to reduce the number of SQL-queries. So there's no need to panic.
