When a new user creates a Pro Site they provide a User Name and an email address to create a user account but no password. I had expected Pro Sites to generate an email to them but it does not. It seems to log them in to the main site without a password. When their Prosite welcome email arrives they are asked to login but don't have a password, forcing (if they are bright) a password recovery. I tried to resolve this using the "Set Password on Multisite Blog Creation" plugin, which does drop a password on the form, but the passwords I enter do not seem to work. Should Pro Site be triggering a registration email? It says it will but mine does not. I have deactivated all plugins to test but still no registration mail. And is there any setting not to have the user automatically logged in on creating their Prosite?
