Recently I have discovered this new feature of PGC. Great! Really much helpful and powerful tool. I like there is no perimeter limit and the format of the incoming mail is just super. Contains all the useful listing info, including geocache location maps with few zoom levels. I like the possibility to set the whole country and all of the types of caches notification in just one request. Very useful nowadays, when new virtuals are coming out. Concerning the daily/monthly usage limits, I have no objection. In my opinion 100/500 is quite enough. My experience is, that there is only and exactly one minute delay of the notification email comparing to the "original" one from the GC site. What I only miss, and consider the essential function, it is not working filter for regions/counties yet. With this filter the feature will become just perfect.
What is your opinion about and experience with the PGC New cache notifier?
