I have a brand new 3.0 installation. I had originally installed MU because I had read that BuddyPress was not yet compatible with 3.0, but apparently that changed just a week or so before my install. I then upgraded to 3.0, added Buddypress, and imported my old content from wordpress.com.
I also have an additional section for classifieds, which has a wordpress bridge. However, a test registration on the classifieds is not recognized on wordpress. That led me to investigate how, or if, people could register themselves on wordpress. I found this: http://codex.wordpress.org/Users_Add_New_SubPanel which says: "If the Anyone can register option is set in the Membership section of Administration > Settings > General, users can register themselves at http://your wordpress url/wp-register.php. "
But when I go to Administration - Settings - General in my dashboard, there is NOTHING about membership anywhere on that page. I see a Users link, and there I see the Add New User Subpanel, but there is still nothing about people adding themselves. I even tried CTRL-F for 'member' in both IE and Chrome. Both told me there was 1 instance of the word on the page, but neither of them would take me there or show it or highlight it.
Do you make a distinction between a member and a user, or are those terms interchangeable? And most important, where is the control that allows me to let members, users, or whatever register themselves?!
