Hello Geocachers,
I have decided to change the caches that I have made "Members Only" back to regular caches. Three of them have been available for close to a year and they haven't experienced problems, and the other has been around for about six months but it is very close to my home and I can replace it in under an hour, if necessary.
Therefore, my experiment has ended. All of my caches are now open to all. I may use the "Members Only" option for a new cache.
