This was one of the promised features from the Geeklog upgrade, and after resolving an issue with the theme, it's finally working -- at least, it's working in my testing. Feel free to leave a comment here and edit it to make sure it works for you, too. Note that there's a one-hour time limit on changes to comments.
We're still working on the character set issue; hope to have progress on that front shortly.
