Christophe Haro asked me a very interesting question today: how does one contact the LibertyEiffel community?
There was no mailing list ten minutes ago. Now there is.
Just write to firstname.lastname@example.org and you're done!
See their site (http://librelist.com) for details. In a nutshell, when you send your first mail you are returned a standard subscription mail; just answer it and you're set.
Welcome on board!
