Remove or Hide Several Profile Fields VB5

[GRAYTech]

I was able to remove/modify several user profile fields by using the "User Profile Field Manager" in Admin CP. Unfortunately date of birth, contact information and web fields are not accessible from the Profile Field Manager. What's the easiest way to remove or hide those fields ?

These fields are default fields and cannot easily be removed.
You could hide them using custom css.

I'm a programmer but not familiar with coding CSS. Can you point me to any resources that might help ?

When I do a VB upgrade in the future will that wipe out any customizations done at that level?
