Still trying to make my username example, google-like.
Google prohibits a very small set of bad words.
I have a BADWORDS working outside of the validation, but when I insert in
validation, I get error.
Any help would be appreciated, I bet it is one little thing :)
I get error
<type 'exceptions.NameError'> name 'BADWORDS' is not defined- Thanks!

*Summary:

badlist = ['frig', 'asdf', 'poop']
BADWORDS = re.compile(r'|'.join(badlist))
auth.settings.table_user.username.requires = [IS_LENGTH(30,6,'Please use
between 6 and 30 characters.'),
IS_MATCH('^[a-z0-9.]*$', error_message='Please use only letters (a-z)
and numbers (0-9), and periods.'),
IS_NOT_EMPTY(error_message='You can\'t leave this empty. '),

has that username. ')

*Complete code, just insert in a new app. like Welcome..*

# | - lower case only [a-z]

# | - can't end in a period
# | - can't start with a period
# | - can't have consecutive periods
# | - min 8 letter password
# | - username can't be changed once registered

# | Note: Messages are nearly same as Google displays
## create all tables needed by auth if not custom tables
# use usernames rather than email addresses to register
