I have actually started putting a note on all of my cache pages directing people to a link on how to log trackables. I'm hoping this catches on, and we can educate people on the go. This is what I put on the page. Copy and paste it if you like, but make sure you click the html box above the description when building the page. Cheers!

If you have found a trackable item and are not sure how to log it, follow this link and read the information on how this works. Please make an effort to properly log travel bugs or geocoins.<br />
