+If you use Triangle, and especially if you use it to accomplish real
+work, I would like very much to hear from you.  A short letter or email
+(to jrs@cs.cmu.edu) describing how you use Triangle will mean a lot to
+me.  The more people I know are using this program, the more easily I can
+justify spending time on improvements and on the three-dimensional

+you on a list to receive email whenever a new version of Triangle is
+available.

+publication, please include an acknowledgment as well.
