/users/new
This request handler creates a new user account and issues
a session key. It assumes that the user creation script
will generate and send a welcome email to the user.
(You can implement an email delivery script in App Engine
if desired). It expects the following parameters:
- username : selected username
- email : email address
- pw : selected password
And the following optional parameters:
- firstname
- lastname
- description
- skype
- facebook
- linkedin
- www
- tags
- city
- state
- country
The script will create the new user, issue a validation key
which will be returned in plain text. It will return an
empty string if user creation failed because the username
was already selected or the password was shorted than 8 chars.
