When someone sends an email message to the mailing list, a copy of that message is broadcast to everyone who is subscribed to that mailing list.
Mailing lists provide a simple and effective communication mechanism.
Every volunteer project obtains its strength from the people involved in it. These people are joined through the mailing lists that they are subscribed to. You can choose to lurk, or actively participate. It's up to you. We ask that you do your best to respect the charter of the appropriate mailing list.
