hey guys, i wanted to activate my MACID however i haven't received my official acceptance letter or email which has the student number and bar code. I only received an email saying "Thank for you accepting ..." which had no information. So i'm not sure if i should wait or not because i need that in order to pick my courses when SOLAR opens up... helpppp !:(

should i call them? if so whats the right phone number to reach them?

If you received an email saying "thank you for accepting", that means you already accepted your offer, which means you already got your admissions package. If you lost that package, call the office of the registrar and ask them to give you the bar code and your student number/ID.
