Whether you are new to geocaching or you just logged your 5,000th find, you will find that questions about geocaching may still arise from time to time. While you probably spend most of your time looking at the individual cache pages on geocaching.com, don't forget about all the tools and information resources that Groundspeak provides and continually updates:
Includes detailed information on "Learning the Basics", "Contributing to Our Community", "Tools and Downloads", and "Third Party Resources".
A great geocaching support center with a searchable knowledgebase, troubleshooter, and download tool.
A fantastic way to get information on a specific geocaching issue or topic from those that have "been there, done that".
The content on all of these sites is continually updated, so if you haven't checked out these resources in a while, it's time for another perusing.
