The owners of all locationless caches, such as the originator of this thread, received an e-mail from Groundspeak on August 15, 2005, to notify them of the upcoming transition to Waymarking.com. Owners were alerted that their caches would be archived at the end of the year, and were offered the opportunity to convert their locationless caches into equivalent Waymarking categories. Owners who were not premium members were offered a free premium membership for a trial period, since at that time the beta version of Waymarking.com was only available to premium members.
So, it is unfortunate that some locationless cache owners did not respond to this invitation by converting over to Waymarking prior to the stated deadline. Hopefully, once the process for establishing new Waymarking categories is up and running, some of these "lost" locationless cache categories can be re-established by new category management groups.
I was not the owner of the LC cache that I mentioned in my original post at the time. I do hope that many of the old "lost" locationless caches can be up and running on Waymarking so that they'll continue to be enjoyed.
