When do I need to log on?      The site needs to know who you are to send a message to or from you, for you to register for an event, or for you to use the contact system.  Users must also be logged on when making additions or changes to the site, although some changes may not take effect until reviewed and approved. What if I am not yet registered (or am not sure whether I am registered)?      Enter your email address above.  The next page will indicate if anyone is already registered at that address, and will also include a link to register as a new user if you are not. Why is my email address used to identify me?      We need to know it anyway, and it is easy for you to remember.  If more than one family member is registered with the same email address, you will be asked on the next page to specify which person you are.  You can specify a password if you want higher security for your personal settings.  We will not provide your email address to people outside ACC or display it directly on the website.   To change registration information, fill in your email address above and then press
