When you add your name to the CCI Alumni page you are asked to create a Username and Password. The same Username and Password are used to post topics and replies on the message boards BUT, oddly enough, if you register your username and password on the Message Forums "only" then you do not "officially" register your name on the CCI Alumni list. So it's best to have registered on the CCI Alumni page before posting Forum messages. (is that confusing enough for everyone)
* Please note that your Username is shown in the Forums (but, of course, not your password).
