I've been dealing something similar for years now. There is a guy out there who thinks that his email address is firstlast@gmail.com, however I've had the first.last@gmail.com version of the address from back before google decided that the dots didn't matter any more. It appears to me that google merged the addresses but he still continues to use the dotless address when signing up for things. It amazes me that he thinks it works, surely none of the email ever gets to it? I've tracked him down on facebook and got a message to him via his wife.... but it continues to happen. Which makes me wonder if somehow sometimes it does work for him?
