IRC is also a part of the staff in residence we're just slightly different.
There's IRC Programmer- which is the inter-residence council member that plans the events and programs that residence students prefer, in short.
IRC Hall Representative- is the inter-council member of the residence that advocates on behalf of students with regards to majors, facilities, food, security, etc etc.
We do far more than that, but you can ask us more about the council (and join it) in September or in this forum!
