usernode

Hi there!
I´ve been searching the forums for a while, and I´m sincerely lost about this issue.

I came to realize that there´s NO WAY to add taxonomy terms to the simple, yet easy, core module "profile".

So, I´ve installed the nodeprofile module. It needs the nodefamily to run, and it suggests you to install the usernode module.
I´ve done all that, and I´ve readed the readme files of all of them.

And yet, I´m clueless about how to replace the profile with all this confusing stuff. I´ve installed three modules already to replace one.
