As the Forum owner, can i manually choose categories for my Forum members to follow?

I run a Forum for 50+ users and sometimes they get confused on how to follow a category. Can i just manually do this behind the scenes? Or do i need their Login/Password? This would be soooo much help if I could just click the categories for each member!
