When things go wrong:

• When you start up rn, you get a "warning" that "bogus newsgroups" are present.

  Within a couple of minutes, you'll be asked whether to keep these or delete them. Delete them. Bogus newsgroups are newsgroups that your system administrator or somebody else has determined are no longer needed.

• While in a newsgroup in rn, you get a message: "skipping unavailable article." This is usually an article that somebody posted and then decided to cancel.

• You upload a text file to your Unix host system for use in a Usenet message or e-mail, and when you or your recipient reads the file, every line ends with a `^M'.

  This happens because Unix handles line endings differently than MS- DOS or Macintosh computers. Most Unix systems have programs to convert incoming files from other computers. To use it, upload your file and then, at your command line, type

  dos2unix filename filename
  

  or

  mac2unix filename filename
  
  
  

  depending on which kind of computer you are using and where filename is the name of the file you've just uploaded. A similar program can prepare text files for downloading to your computer, for example:

  unix2dos filename filename
  

  or

  unix2mac filename filename
  
  
  

  will ensure that a text file you are about to get will not come out looking odd on your computer.
