The Honyaku mailing list is currently hosted by Google Groups, which has a straightforward web-based system for subscribing, unsubscribing, and managing your list preferences . I recommend doing it via the web, but you can do it the old-fashioned way by e-mail, too--see below.

Google Groups has its own FAQ for basic subscription mechanics at http://groups.google.com/support/

How do I subscribe?

To subscribe to the Honyaku mailing list, send an e-mail message to:
honyaku-subscribe@googlegroups.com

This message must be from the address you want to use, but can contain any kind of message

How do I post messages?

When you are subscribed to the list, you can post your own messages for distribution to everyone else. Send your post to:
honyaku@googlegroups.com

You must send your post from the same e-mail address at which you subscribed to Honyaku.

How do I unsubscribe?

To unsubscribe from the Honyaku mailing list, send an e-mail message to:
honyaku-unsubscribe@googlegroups.com

This message must be from the address you subscribed from, but can contain any kind of message

How do I set my list options?

As near as I can tell, this is something that you must handle via the Google Groups website. You can choose to have mail delivery stopped (but can still read messages on the web), or have digest delivery.
