Lots of new stuff on your Edit Profile page:

You can now link your old digibutter account to your account here.  This will help people know who you are and let you claim your old username.  It will also set your joined date and may be used in the future for rewards and to pull down other stats.  I will eventually remove this ability, so link it while you can!

You can also set your username (it defaults to random letters & numbers).  This will help us tell people apart even if they have the same name, since no one can have the same username.  Also the link to your user profile is now easier to remember... digibutter.nerr.biz/profile/username 

In addition to your username, you can set a password.  So you can now login using a regular username/password as an alternative to OpenID.  This is a good backup incase your OpenID provider stops working.  Click the old-school login link at the bottom of the Sign In page.
