where to get my.seneca id??

a friend of mine recently applied to seneca and because im @ york and this is her first year...we're both unsure on where to get everything needed in the process of applying..

i know its really late for her but anyways where can we registar for the "Siiris My.Seneca (Learn) ID and password" ?

im not sure where to begin looking on their site but on the Siris login page it says to contact the student services centre to find out where to get it...do we have to call them? do we actually have to physically go to seneca to registar for an account?
