I got a number of errors trying to use this... I'm pretty sure I have it all setup correctly with the QueryPath module installed too.

Here were the errors (all the "required fields" were filled in so not sure why those came up too):

* user warning: Duplicate entry 'nfd.twitter@gmail.com' for key 2 query: INSERT INTO users (name, pass, mail, status, created) VALUES ('nfd.twitter@gmail.com', 'a8fbf908c49bb7dc51cf6437c5e7f22f', 'nfd.twitter@gmail.com', 1, 1278430993) in /home/natedame/seoperks/modules/user/user.module on line 327.
* Unable to send e-mail. Please contact the site administrator if the problem persists.
* Validation error, please try again. If this error persists, please contact the site administrator.
* Campaign Description (displayed on your account screens for easy reference) field is required.
* URL field is required.
* Title field is required.

I used a brand new email to register with, added a password and hit Register -- nothing happened. Then tried to hit Save and that's when these errors popped up.

Thanks!!! GREAT MODULE! Can't wait to get it working.
