Usenet

Usenet News groups are one of the many facilities available on the Internet. Like most of the Internet, Usenet News groups are run voluntarily & co-operatively by people like you & me. A News group is centered on a discussion topic an example being rec.sport.soccer. Within these News groups several discussions or Threads take place on themes within the discussion topic. A news group devoted to the great rock guitarists may have a thread on who is the best guitarist out of Clapton, Beck & Page for instance. If you are having a problem getting something specific to work in a spreadsheet there will definitely be a news group to which you can pose your problem & it won't take long to get many responses. Unfortunately news groups appear to be the vehicle for a majority of the more undesirable topics that pollute the Internet. If you see a particular News group of interest you can "subscribe" to it. Once this has been done you "post" your article & eventually it can be seen by anyone else who subscribes to the particular news group. The categories of News groups (represented by the first 3 or 4 characters of the name followed by a "". are): rec - recreational activities; biz - business related groups; comp - computers including technical discussion & support; soc - social issues; sci - scientific discussions; uk - groups of interest to us English, Scottish, Irish & Welsh; alt - Alternative groups.
