Tommy,
When I hit reply to one of the posts in my mailbox, will I then reply to eg. Kim, or Rob or will it go directly to the list.
Do I need to create a new mail to the list if I want to answer on something for everyone to read??
If you simply "Reply," the message is likely to go only to the person who sent the message you're replying to.
If you "Reply All" however, the message should go to the list as well.
Some mailing lists are set up with a Reply-To: header so that by default all replies will go to the list. That's not the case on empeg-dev, at least not now -- I'm undecided whether I should change this.
If anyone has an opinion, I'm happy to hear it. Otherwise it's assumed you are careful to reply in the right way.
(One argument in favor of an automatic Reply-To: is that some people are annoyed to receive two messages when the message is addressed both to them and to the list. As a courtesy, it's often a good idea to trim the To: and Cc: lists when you know someone is subscribed to the list.)
