Arlington Toastmasters

I tried registering for the Arlington Toastmasters but I got an error message that the email does not exist. Please advise.

we always require your club number or we can not assist you.

I don't have a club number because I would like to join a session as a guest for free to learn more about the benefits of Toastmasters. I tried to register for the Arlington toastmasters but the email does not work. Instead, I registered for the Stamford, CT toastmasters although that is not preferred.

This is not a toastmasters club.
