Can I use my PC at home or in my study bedroom to access my CSiT email?
Yes you can. The quick and easy way to do this as a one-off is simply to connect to your home UNIX server using a telnet client and use MH commands as details here: http://www.cs.nott.ac.uk/TSG/intro_docs/mh.html. You can configure an email client such as Netscape to access your email instead, most people prefer this method when checking email on a regular basis. You can find details of how to configure Netscape and other IMAP clients to read your email here: http://www.cs.nott.ac.
