I sent an invitation to a new user to be an editor of my blog. The new user does not have a wordpress.com account, so I put in his email address. When he accepted the invitation, he was asked to login. He does not have a username and password so hetried to register but it says that his email address is already registered. What should he do?
I already deleted the invitation, but when he tried to make a wordpress.com account it still said that his email is already being used.
