We've just added a new profile section - "My ID DeLorme Progress" which maps your progress on GCQVXZ - Idaho's DeLorme Challenge. As with any brand new section, if you'd like to start displaying it on your geocaching.com profile, you'll need to re-copy/paste your profile's HTML code from the mygeocachingprofile.com "Preview and Export Profile" page over to your geocaching.com profile.
If you have any questions or problems with the new feature - Contact Us or visit our Help page.
