You mean get to the admin screens? If you're logged in as the administrator there's a link at the bottom of the forums pages that reads "Go to Administration Panel". It's a link to http://forums.example.tld/admin/index.php. You will have to log in again.
Of course, you could always just go straight in to http://forums.stromgarde.org/admin/
Or do you mean that you forgot your admin login and password?
