Hi there,
Although the plugin page says it only works until wp 2.9.2, i tested in wp 3.3.1 and all seems to work just fine. I became a little confused: it’s not updated because its not needed or i just had “lucky” and it worked? If it’s the first case, maybe the author could confirm its working in newer wordpress versions and make an update just so everyone can know the plugin is working.
Thanks
