The feature I have been missing the most in new cache notifiers is the option to get an email when a certain owner has published a new cache. I have a bunch of owners I like a lot and would be glad to receive a notification if one of them has created a new cache. With only geography-based filtering I get a lot of false positives.
It would be fantastic if I could set up a list of cache owners in the PCG new cache notifier section and get an email if one of these owners has published something new. Additional filtering for cache type would also be nice.
I hope also other users might find this an useful feature.
