I've written a small amount of Emacs-Lisp, none of it particularly noteworthy, since I'm not a particularly experienced Lisper, but hopefully it's useful nonetheless.
If you haven't used or heard of goofey, this won't be much use to you. Many years ago, I wrote a small piece of code that let me send (but not receive) goofey messages from inside Emacs. I revisited it in 1998/1999, and added a lot more functionality, although there's much more that could be done with it. I've written this under XEmacs - it used to work under Emacs once upon a time, but I'm not entirely sure these days...

Sometime around mid-1997, after having to play with
Directory Servers and the like for my work, I decided it'd be
nice to have Emacs play along. It just calls an external
program (ldapsearch, which comes as part of the OpenLDAP distribution) to do
the work, and parses the output.
Note : This is old. You should go and use
Oscar Figueiredo's EUDC.
It has a better interface to the external
ldapsearch, and can also use XEmacs' built-in LDAP
support (which he also wrote).

Noah Friedman wrote some code to parse vcard information, along with some hooks for the VM mailer. There weren't any hooks for TM (so I could use it with Gnus), so I figured I'd give it a whirl. The result's pretty basic, but still functional.
Note : You don't need this if you have Gnus 5.8.x - I provided a patch during the development phase that displays VCards using Gnus' new MIME routines.

A friend asked me to write him a bit of elisp to save the
current buffer to a file and run install-memo (from
the pilot-link package) to upload it to his Palm Pilot. There's
also a little hook into Gnus so you can say "save this article
off to my Pilot". Last time I touched it, it worked on both
Emacs 20.4 and XEmacs 21.x.
