I installed WP using subdirectories but Google's new world seems to be pushing subdomains for my application. I have 2 questions:
(1) I've seen a couple of "simple" ways to convert an install of a subdomain to a subdirectory. Do any of these actually work? I'm wondering whether a simpler way might be exporting the contents of a blog into a file and then reimporting them into the new blog in the subdomain.
(2) Is there a way to have a unified login so that if you register for one "blog" you are entered into all the other blogs? I don't need separate logins for each blog/subdomain.
Thanks to all for responses.
