How do I remove the telephone number field from signup?

finally, a simple solution, thanks a lot. This really should be an option in Admin I think.

I just did this in version 1.5.7d. Agreed, it should be an admin function.

Since without a valid phone number, there is no accurate way to contact a customer with any problems, questions, or corroborations, I doubt you will ever see that happen.
