I have a friend whose Gmail account name is a fairly cryptic series of letters, and who filled out equally cryptic strings when Google asked for his first and last name, so that emails come from something like
ilkwekjr nsdkfjlk <[email protected]>. He also doesn't have a Gmail signature.
When I mention that this makes it hard for people to know where his emails come from, he claims that he does this so he can comment on YouTube videos without his real name being visible.
What are the current rules/limitations about having one's Gmail name/address visible when one comments on a YouTube video? Or, how can one add identifying email to a Gmail account without it showing up when one comments on a YouTube video?
