just 2 cents: guys, please don't mix up validity and conformity to business rules. sometimes it's hard to not to mix them up, but it is important doe distinguish. That a form field should be an email address is the first one, that this address should be unique in the system, is the other thing. Validation proves the format and type of the data, Businessrules proves integrity of the data model. first is made by simple sync functions, the second one needs interaction with the business model layer including db-access.
