Actually, you do have access to the web (just not the graphics).
When you log into dimacs, type the command
lynx
Forward and backward arrow keys work like Netscape's
forward/backward buttons; up and down arrow keys move you among the
links on a page. Press "g" to go to a specific web address
(http://...).
I agree with you though that email is great for notification. It
might be good to set up the site so that people can request email
notification about what's new there.
