The logo image in my email address signature line broke. What happened ?
Click on the Settings Icon and then select Settings.
Scrolling about halfway down the page, you'll find Signature:.
Remove the original image that is now broken.
The NEIU logo graphic can be added using the 'insert image' icon. The NEIU logo graphic can be found at http://homepages.neiu.edu/~neiutemp/nmail/neiu_new%20logo.png.
The original link supplied was http://www.neiu.edu/~neiutemp and that url no longer works.
Warning: Cutting and pasting the text and links from outlook into NMail has caused problems for some people so it might be best to avoid that and just start from scratch.
