When you disable signup that mean only public users can not register.

Site administrator can add users from administrator panel -> Users -> Add User

or scroll down on his website

then you got his email and tel.no

yes, he got an email that someone had made a reply to his topic

how do I contact him? do I just add a reply to his discussion?

get in contact with Blaine Klingaman

i think he did it all ready, see topik

thank you so much for your reply. How do I do that? I am not good with codes etc.

email-invite everyone with an unique activation link to your OSSN, before you send your invitation, you have to make the activation link from username and password with md5 or something and a small php script file where the activation link goes to. This file register the users username and password in OSSN then they can login.

if you disable signup all together how can I add people from my company?

or you can try this component

Thank you for your reply.

I only want it so only people in my company can register. Perhaps take away the sign up form and do it so I can invite people.
