Can't we mix and mingle?

I told a friend about this site in the hopes that she too, would find the help and support and friends as I have in here. Her disease was not listed, so I wrote and asked that her condition be added. And they did. I forwarded the information for her to sign up, and went to the link and there was no button to hit to join, and when I signed in as a member, ti says I'm not a member. Yet here I am... on my own page as a member of the CIDP survivors page. Can I not join her page and her mine so we can both navigate this site to get the full benefit? The links I did try to use asked me to sign up with the information I used to get here. Is it separate? I'm confused... just a tad. ~ Sis
