I am a new member here. I am also new on discourse. I bought a server with installed discourse. Because of send out mail problem I can not invite new members. I see user and system on the users page. I can not manage system user. And there is no email defined. Fot eh second user is user. It has mail defined email@example.com. I can not change it. It asks need to sonfirm the sending mail activations etc. How can I manage these all?
