XF 1.5 User profile fields

How can I customize the profile fields? I'm not looking to add new ones, just disable/delete their ability to add a homepage and AIM. Is that a template fix? I can't find anything in the ACP options.
Thanks! I managed to remove the homepage from the template.
Where are the settings for the custom user fields? Can't find them anywhere :oops:
I <xen: comment> the homepage section in the Member Search add-on I am using. Still don't know which XF template that would be. All good!
