Cr@ZyBoYHi! I have a little problem - my blog (not MU) uses wp-subdomains plugin. As you know, after you log in, "Login / Registration" converts to "Logout / Site admin". But it works only on the main domain. If you are logged in but on the subdomain, those links become "Login / Registration" again. How to make wp_loginout and wp_register functions work correctly on subdomains?
