How do I make some user fields not required

There is no reason for my store to collect telephone numbers or addresses. How do I un-require them? I can only do that with some fields in the configuration area of the admin, but not all of them. 

Note: our product is downloadable, used exclusively in nonprofit circumstances, and we do not collect taxes.

Dear spitjack,

Thank you for submitting the question here. Regarding your question: You can go to EShop -> Sales -> Fields to unpublish / unrequire the fields that you want.

I hope this is useful.

Sincerely, Giang

That works on the address tab, but not the user field. On the user field I still get:

Hello spitjack,

Yes, the fields are only applied to address. The user fields are fixed.

Sincerely, Giang

We have no need of their phone number - can I override and make this nuisance demand simply disappear?

Hi spitjack,

If you want that, you can override or modify to EShop to implement.

Sincerely, Giang
