Hi Joffroi, It's in the permissions setting. system --> users --> create permission. The "newly created user" is at the top of the list in the permissions popup
I saw you were helping out someone with this a while ago: http://forums.movabletype.org/new-design/2008/08/user-registration-and-authenti.html I am having the same problem. Where is this newly create user role that we can edit? Thanks
