I remember people asking for one of these on this list.
As I had a few days on hand and have always wanted to try my hand at
writing a mode. I wrote one for remind.
It has only been tested on GNU Emacs 22.1.50.1
(i486-pc-linux-gnu, GTK+ Version 2.11.6). But I don't really anticipate
any problems as there are no surprising code. I suppose it might not be
very useful for those who use emacs-nox. But, such as it is.
There is one skeleton script (rem-skel) for entering a simple REM line
in a configuration file. The keybinding for it is "\C-cr"
Things that could be improved. My regexp expertise is small, so some of
my attempts at highlighting functions are faulty.
Let me know how well it works for you.

;;; Commentary:
;; Use this mode to help with the configuration of remind configuration files.
;; Put (require 'remind-conf-mode) in your .emacs file
;; also put (add-to-list 'auto-mode-alist '("\\.rem$" . remind-conf-mode))
;; (add-to-list 'auto-mode-alist '("~/.reminders$" . remind-conf-mode)) if you
;; want to have the mode work automatically when you open a remind configuration file.

;; Based mode on wpld-mode tutorial and simple-mode on emacs wiki.
;; Ideas from mupad.el for font-lock styles.
