I am about to roll out 1.9 to our organization. I see the 143 employees under User Directory and they are all listed as guests. I need them all to be registered users. I know I can do them individually, either by registering them myself, or sending them a link to register. My question is, is there a way to send out a mass e-mail to everyone asking them to register? Right now I only see a way to do it one by one. Thanks.
