The Computing Service have provided a nice guide on how to find people electronically in Cambridge University.
There are lots of local newsgroups in Cambridge, including:
- ucam.chat for discussion within the University. It also has a home page
- cam.misc for more general discussion (FAQ), except
- rants about traffic, buses, cyclists, taxi drivers (...) which belong in cam.transport
