Is Monthly Chess Mentor automatically renewed?

I was trying to use Chess Mentor for a month, started Dec. 26, 2007.  Today I received an email message, saying that Chess Mentor montly renewal was successfully completed.  Obviously, Chess.com remembers my credit card information and charged it the fee for another month of Chess Mentor. 

It is OK for me to pay Chess Mentor for another month.  But, enough is enough.  I actually don't have much time to work with Chess Mentor.  I would like to spend my time to read the chess books, and study in some other ways.  How could I end the training (paying) of Chess Mentor someday?

Thanks for the help in advance! 

Maybe I put the question into a wrong place.  

Did anyone know about the answer?

Thanks Erik for the reply.

So if I don't ask, the renewal is automatically done every month. 

Where should I send my request to for cancelling my Chess Mentor program?   Who are them?  :-)

Yes, your Chess Mentor monthly subscription will be automatically renewed each month unless you indicate to us that you would like it to end. You can do this by contacting Chess.com Support by using this link:

Thanks Patzer24.

I would like to say that the Chess Mentor program is really helpful.  But my time and my finance are all limited.  Thank you for the good program!
