Not really.

Best thing I can show you is to give you the actual Your_Account module I made:

This probably wont work on any other nuke but the one we're using (Raven Nuke)/

Now this just prevents registration of fake accounts.  Basically:

- We don't allow you to post unless you have an account.

- When you register there's better CAPTCHA than default.  Plus a bunch of checks for your username, email address and IP address.

- When you register there's a email confirmation check (this no longer works well).
