[How to change my username]

You can't.

 

You'd have to create another account and then (if you'd like) log those caches you found with this one. When logging back those caches, you'd probably have to explain why are you doing that. It's a bit of pain...

Thanks for the quick reply. I think it was possible to do it in the past (I seem to recall I did it in my greenhorn days). So much for my wife's idea of "Mr. and Mrs. Big G".

Now I'll probably have to buy her a GPS so she can log her own...

Can I change my username on geocaching.com?

If so, how?

Thanks in advance.
