You can't turn on register globals (Or any PHP configuration settings) from an .htaccess file. PHP is not set up as an Apache (HTTP server) module, thus you cannot.
Register Globals can be a huge security risk anyway. Why would you want to enable it? In my opinion it is easier just to code securely and more efficiently without it on.
Also, sorry that no one saw this thread. Some of us have lives and can't check for new threads and ones we missed every day. If you want to take your "business and friends" elsewhere to another host, go for it. Another staff member or myself will be happy to help you out by terminating your account.
