Q. where are links to D2L and NMail on the new website?
The new website is intended for prospective students and future employees. since neither would ever use Desire 2 Learn or NMail, the links were not included. You'll probably also note that a lot of information targeted to current employees and registered srtudents is also no longer included, that information can also be found in NEIUport now.
NEIUport is one option to easily access these links.
In addition, they can be easily added as bookmarks on your favorite browser.
