Facebook.com won't let me change my last name a a single letter (against their rules, or something). But, I've seen a lot of people with single letter last names...
How do I change my last name to just the first letter?
Ho do you change your last name on Facebook to a single letter?
I would try putting in m last name and then put dots next to it or something what ever the person did they are slick or it could actually be there middle initial . That is what i am more inclined to believe.
Reply:You can't do that anymore. The other who have only the first inital of the last name hasn't changed their name since the rule went into effect. let's protest that rule!
Reply:If you go to "account" in the top right corner, the first option is "real name", if you change it to (Name) (first initial), that's your display name. It may take a few hours or a day to change htough.
