Displaying just your first/last name on Facebook?
 

Hi

Is it possible to just display your first or just last name on Facebook?
Or register a new account with just one name?

I tried using hidden space symbols, but it doesn't work.

No its not. The most you can do to conceal your identity is only use an initial for your first or last name. Or if you really don't want your identity known, just make something up.
