Here are my settings files for Emacs that I use as an editor pretty much everywhere. The gnus file is only necessary if you intend to read your mail and Usenet news from your Emacsen. Otherwise the emacs configuration file is quite enough.
Download them and place them in your home directory, rename them to .emacs and .gnus and then play along with them. If you already have your configuration files there, please make sure you back them up first.
