I have installed this module: captcha-number-subject-combo-in-one-1.0 and it works great! I need this for the anti-spam.

I also like the ability of having the phone number and subject field. However, I don't want the phone number to be required on the contact us form page (only required for create an account).

I could not find a support thread for this module. Any ideas as to how to remove the phone number requirement?
