I must be skipping too many threads, I have seen very few heated arguments here. :p
Anyway, back to the original topic, I have suggested the same thing and practice it on a regular basis. I originally posted it in my http://www.geocachingmaine.org/forum...ead.php?t=1564 article:
13. Communication! Check your gc.com emails on a regular basis. Respond to emails concerning your caches. Send emails to finders if you have questions or just want to congratulate them - if your cache is their first, send an email welcoming them to the sport, and invite them to join Geocaching Maine! Be friendly and fair if there is a disagreement. If you are not willing to do this, don't place a cache!
