[quote]Virtual caches and webcam caches are no longer available as options for new listings on Geocaching.com. Caches of these types that existed prior to November 2005, often referred to as grandfathered caches, are exceptions to this rule and may still be active. New listings similar to these cache types can be created as waymarks at Waymarking.com.[/quote]
All other cache types except Earthcaches must contain a logbook and container for people to sign to claim a find. http://www.geocaching.com/about/guidelines.aspx?expand=1#logging
Please contact me within the next month if you wish to unarchive this cache once you have replaced the container.
