If you are having trouble logging in - but you have the right username and password - I recommend you close all of your windows, especially Internet browser windows, and then reopen just one.
Go to the first page of these message boards:
CruiseMates Cruise Community and Forums - Powered by vBulletin
This is the page has the listings of all the topics - not the page that may have the "error message" and asks you to log in. The instructions say to hit the back button if your log in does not work - so DO THAT.
Your username should fill itself in again, type in your password, BE SURE TO CHECK "REMEMBER ME" - and hit "submit"
That worked for me after several somewhat various missteps.
