Geocaching Australia

OH! that's how it works, I get now, thanks for the clarification and help.

Here is whats on my screen under my original cacher name ziggy_k same results appear when I try to change to b4today (cacher search does not show already exists) When I click on the update button all seems fine it's when I log in again that the errors show. As yet I have not had any finds on either ...

Could I please have my geocaching name changed from ziggy_k to b4today, I have tried the self-service function
but that has only produced errors and all my details disappear.
I wish to retain ziggy_k as my forum name. Thank you.
