I just can't figure out how for the views argument to user the "Like" operator instead of "=" operator.

I would like to have a view that lists all the users that start with the alphabetical letter that is sent via the URL.

The SQL would end up being ..

SELECT users.uid AS uid,
users.name AS users_name
FROM users users
WHERE users.name Like 'A%'

Any help or direction is appreciated.

I am developing a new Drupal theme for my site that will use the Blueprint framework.

Should I start from scratch, or should I use the Drupal Blueprint Theme?

I only ask because Bob has said in one of his videos that you shouldn't use other people's themes because you don't know what's in them ... But I wasn't sure if that was the case with the Drupal Blueprint Theme.

Thank you
