21:  Where can I get help in installing Emacs?

  See question 81 for some basic installation hints, and question 83 if you
  have problems with the installation.

  The file etc/SERVICE (see question 4 if you're not sure where that is)
  lists companies and individuals willing to sell you help in installing or
  using Emacs.  An up-to-date version this file is available on
  prep.ai.mit.edu (see question 20).
