The Node Age filter only allows you to set the age within the past 24 weeks (or newer). We have a 12 year old forum, and 24 weeks is not very old in this context. I would like to be able to set this in the years (e.g. 1 year for "old", 3 years for "really old").

It would also be nice to be able to set percentages lower than 60% (e.g. 50% for "old").
