OK, the topic title might be quite confusing.
Here is the thing: I want to create 3 different blogs. What I want is to log in to WP using just ONE username but show publicly THREE different names. This is how it would work. I want Blog 1 to show me as author with name X, Blog 2 with name Y, and Blog 3 with name Z. I do not want people who read Blog 1 know that I am also the author of Blog 2 and 3 and vice versa. But I do not want to have three different login usernames in order to access the control panel.
And the question is, would that be possible?
