Most people are familiar with the Netscape navigator also available in UNIX. Type
netscape &
to let it run in the background as any other X-windows application.
In case the X-windows environment is not available or it is very slow,
knowledge of applications such as lynx allowing browse the web or read a newsgroup
without X-windows is helpful. To read a newsgroup one may use pine or trn.
For example
trn cs241
opens the cs241 newsgroup. Help while running trn is available by pressing 'H' To send a message to a newsgroup use 'f' or 'F', to read the next message, press 'n', to quit trn press 'q'.
