The latest updates to the new user management function being developed for RavenNuke™ include inline validation and a password strength meter for new user registration.  Most fields are validated as you enter them, and a new user cannot proceed until resolving the issues.  This uses the powerful jQuery javascript library, but server validation remains for those users who have JS disabled.  As a side benefit, the table format was converted to a fieldset with CSS, making this form more accessible as well as easier to customize.
