Jedi Caching Powers

http://www.geocaching.com/seek/cache_detai...76-dfbaece21e19 Taking her with me was geocaching comedy gold!

So I signed up and gave geocaching a try, 25 caches in i'm loving it and am doing it more and more. So now I want to get myself a personalised stamp for logbooks, but with a different name. So... Is there any way I can change my username? If I have to create a new account, is there any way I can transfer my caching history? I dont want to go back to 0 found! Thanks in advance for any help

Unhill Bole was a big cache I found recently with an array of great items inside, decks of cards, a rubix cube, soft toys, all sorts! Its not too far from London and part of a series the Moulsford Downs, a nice countryside walk of 14 caches over about 5 miles, circular taking you right back to your car! so you could make an afternoon of it?
