[Mailman-Users] problems

[Thugworld2]

im new using this feature. All I want is for members of my site to sign up and only I can send emails to the members. The problem is that instead of subscribing members keep sending to entire list and I have to go retreive it from pending. I turned the feature off but it still goes through they just dont understand to join you have to enter in a password etc Also why do I have to approve sending my own messages to group
