Hi Abe1,
Actually I ported your groan hack to vb3.7 several months ago but didn't publish it. The groan and thank you hack would work similarly to
Seba's postrate hack . IMO, your groan/thank hacks have better coding style and are move actively developed. However Seba's postrate has one very nice feature: it auto-hides posts if they are below a defined score. If you can adapt this idea and combine groan/thank you hacks and have post auto-hide feature, that will be great.
