Usenet DnNewsgroups are similar to discussion lists except that 
usenet uses it own network rather that electronic mail to distribute the 
information. Each host maintains all newsgroup files (the host decides how 
long to save the files, usually about 2 weeks). Users read the files from 
the host's database and keeps a file in their space with just the names of 
subscribed groups. Users access the newsgroups using a newsreader. The 
newsreader we will use is called tin. To access tin just type tin at the
unix prompt. Tin will now display all your subscribed newgroups. 
(Sometime before doing this tin will display some new newsgroups. You can 
decide to subscribe to them (one at a time) or type q.) As with 
the other tools command information is displayed at the bottom 
of the screen.
Some useful tin commands 
up and down arrows		-- used to highlight items
left arrow			-- select highlighted item
right arrow			-- go back to previous item
s(while reading index)		-- subscribe to newsgroup
u(while reading index)		-- unsubscribe from newsgroup
y(while reading index)		-- toggle between all and subscribed 
				-- newsgroups 
r(while reading index)		-- toggle between read and unread 
				-- postings
w				-- post to the newsgroup
s(while reading a posting) 	-- save to a unix file NOTE:the files 
				-- are saved in the (sub)directory News
h				-- list all commands


NOTE:	Newsgroups can be read and posted to via lynx by typing

	lynx news:name-of-newsgroup

	at the unix prompt.
