I have two wordpress blogs, let's call them blog1 and blog2, both registered under the blog1 username.
I want to post as username "blog1" in blog1, and I want to post as username "blog2" in blog2.
I have searched through the support forum and tried to set up a new account with the username "blog2" (intending to add blog2 as an author) but I am getting an error message saying blog2 is already taken (probably by me since I have the blog name blog2.wordpress.com registered). HOWEVER, when I try to log out of blog1 and then log in with the blog2 username, I get an error saying that username is invalid.
Help! Thanks so much.
