User settings

I was trying to see there was any way to have users access the word press settings page thru the Subscribe2 plugin. In other words, I wouldn’t want them to enter their email address thru the Subscribe2 widget and still have to register at the Word Press page. Is there anyway for me to give them the ability to manage their users settings, (Categories they subscribe to etc) for the Subscribe2 form?
