Several of my own geocaches have been found recently (I checked the logs for the cache listings), and although the listing shows the new logs, I have not received email notifications for all of them. This sounds like similar problems that other geocachers have had with their logs not showing up.
Also, I have created an Adventure Lab Cache which has been successfully completed by two players. However, the tally of my finds listed on the Lab Cache Builder site differs considerably (by several hundred fewer) from my actual find tally.
