Tin is a newsreader available on mail.sas.
Selecting a Newsgroup to read There are thousands of newsgroups which cover different interest areas. If you have never used tin from your mail.sas account, the system will automatically subscribe you to a few important groups and some newsgroups of local interest, such as news.announce.newusers , upenn.general , and upenn.sas.mailsas . You can either be subscribed or unsubscribed to a newsgroup. Every time you start tin, you will be asked, for each newsgroup that has been formed since you last read news, if you want to subscribe to the new newsgroup. To bypass this part of the initialization, press q at any query.
