If you saw an error message when you tried to register on the Classmates site, the email address you provided might already be in use on the website. It's also possible that your email provider could have requested that their addresses not be used to create Classmates memberships, or the address is not recognized as valid.
Note: We only allow one email address to be linked to a membership so we can make sure any email we send reaches the right person. If you share an email address with someone who's already registered, you'll need to use a different address.
We encourage you to try registering again using an alternate email address. If you don't have one, we suggest setting one up with a web-based email provider (Gmail, Yahoo, and others offer free services).
If you think you might have already registered using the same email address, try to log in now, and request your password if needed.
