I'm following the tutorial here :http://www.getfuelcms.com/user_guide/modules/tutorial and I was trying to enter an email address with a .info TDL and it failed validation for an author. Not sure if that's with how you're validation works or CI's validation.
It looks like there may be an issue with the validator_helpers valid_email function. What happens if you change the last part of the regular expression from {2,3} to {2,4} on line 29 of the fuel/application/helpers/validator_helper.php file?

I'm amazed at how fast you reply to questions on here.
