What to do on this day:

http://www.fsf.org/events/thank-a-developer-day
This page says: "Send a thank you E-mail to a developer."
(This page should be translated to Chinese.)

We can send messages to authors and translators of free documents.

We can add thank you messages to our web sites:
"This page is powered by [program name]  Thank you, [developer name]"
这网站使用[自由软件名]   多谢[开发者名]

We can discuss with our friends about programs and features we use
every day.  We use some tools so much that we forget that they did not
exist before someone invented them.
