The College site has information on:
For any problems regarding computing you should visit the Computing Office (adjacent to the College Computer Room) or email firstname.lastname@example.org.
There are two: the main one is located in the Theatre Basement, which is in the same building as the Ward Library. To get to it, go down the ramp between the Theatre/Library and Fen Court (as if you were going to the Granta Place gate). Just before the gate there are a pair of black doors on the right; go through these doors and the Computer Room is the first door on the right - access it using your University Card.
The second one is in the Gunn Gallery, within the Library.
Both rooms have a printer, scanner, and photocopier, in addition to computers which are available for student use. For A3 printing,
use the computer room located in the Theatre Basement.
To manage your mailing list subscriptions (unsubscribe or subscribe), go to lists.cam.ac.uk or srcf.net. Note that new users do not need to subscribe to any official Peterhouse mailing lists, such as email@example.com (the mailing list for all Peterhouse undergraduates). This is all done automatically.
To set up an email list for a club or society you need to request that the Computing Service set up the list and approve it, then add the list members and set the list operation settings. The first step is to get the list created by the Computing Service so you can fill it with addresses. You can apply for a list address by filling in the form as detailed on here. More details on restrictions on lists and how they work can be found here.
The Student-Run Computing Facility (SRCF) exists as a university society to provide useful, flexible computing and network services for University of Cambridge Staff and Students of all degrees of ability. If you want to make a website for a society, the SRCF provide servers for free to host the site.
