Did you know that you can forward emails from another account to your HYMS email address, or vice versa? This can make life easier for you, for example by receiving emails from the university libraries at your HYMS email address rather than needing to check your university account.
Instructions for forwarding emails are available here:
From a HYMS account to university accounts at http://help.hyms.ac.uk/staff/helpsheets/email-forwarding
From a University of York account to a HYMS account at http://www.york.ac.uk/it-services/facilities/account/ (or, if you're using Gmail, click on the cog, then Mail settings and then Forwarding and POP/IMAP. Then click on the "Add a forwarding address" button).
From a University of Hull account to a HYMS account at http://www2.hull.ac.uk/acs/help/university_email/email_faqs.aspx#autoforward
