The School of Mathematics, as well as the University administration, frequently send information, reminders, and requests to students via e-mail. You are therefore required to check your University e-mail account frequently (preferably daily) and reply when requested. Here are the University guidelines on the use of e-mail.
To have your University e-mail messages forwarded to a different account, logon to your University Webmail account, go to OPTIONS, then FILTERS, then FORWARD. For more details see  this ISS document.
