"Clever" validation drives me mad. I once had to fill out x pages online and than the system was not accepting my correct email-address. Or a shop wouldn't take my order cause the bank account number had an "unusual" pattern. It was a correct bank account number but the programmer of the shop knew it better. The little shop was Amazon and it took them a long time to correct this.tammo wrote: You convinced me: I will "validate" by making the user fill in twice.
Our surveys may not have that impact but using all this clever stuff can cause pain on the other said (as my posts do from time to time).

These email-adresses are possible and technically valid. Not that they are the most common once, but since developers sometimes want to rule the world with one RegEx these are nice testobjects.
