                        <p>
                            A Site ID is a short identifier with no spaces or special
                            characters other than periods or dashes. It is case-sensitive and we
                            suggest sticking to lower case letters for ease of use.
                        </p>
                        <p>
                            If each site will have its own host/domain name, then use that
                            name as the Site ID (e.g. www.example.com).
                        </p>
                        <p>
                            The site ID is used to identify which site you will log in to.
                            If it is a hostname then it is taken from the hostname in the URL.
                            Otherwise you must append "?site=<i>siteid</i>" to the URL used for
                            logging in.

                        <p>
                            It is OK for one of the sites to have "default" as its ID. This
                            is the ID that will be used if it cannot otherwise be determined.
