Tip:
In your Kiva.org profile settings page (where you can edit your profile info), you can also edit the address of your profile. For example if your profile is:
http://wwww.kiva.org/lender/john1234 then you can edit the "john1234" part to be something prettier like your username, or your first name last initial. This will take effect once you click save- however, I believe it will not work if the thing you chose is already taken by someone else (I've never experimented with that).
This might interest people who have lender pages used by groups, organizations, or people who just want a nicer URL for their lender page.
