Oh, and welcome to Geocaching Maine!

Yes, welcome to Geocaching Maine. TFTC = thanks for the cache; TNLNSL = took nothing, left nothing,signed log; TB = travel bug and there are many more. I haven't looked at the page G Team suggested but keep asking question and reading. Also, if you can attend an event or two, meet folks and ask questions.
