The Math Department provides computer accounts to all its faculty, staff, graduate students, and visitors.
However, our email servers have been integrated with DoIT's, so you can get a math department alias to your firstname.lastname@example.org.
Honorary fellows can get accounts, too, if their sponsor requests it.
However, they need to get a zero-dollar appointment through the college to get a netid. See Payroll about getting a zero-dollar appointment for a visitor.
