How do I accept admission to Cal Poly?

On the cal poly portal (my.calpoly.edu) it said i was accepted for early admissions and must accept/decline before January 15. It says to accept or decline on the portal page, but when im on the portal page I dont see anything that will let me make the decision. It frightens me a little bit because getting accepted to cal poly slo was a big deal for me and so I would just like to be sure that I am in. Please help.
