Title says it all, hope this is possible as I want to start a network of sites for different stuff but want to use one account system with that subdomain using ssl with extended verification, thanks. EDIT: Ok, it has been closed because I am not being clear enough so I will narrow it down a bit more. I am wondering how to move all registration files and login files into a sub-domain instead of just the normal domain so I can put an SSL on it to make it more secure but leave the rest of the blog on the normal domain.
