Join via the group page:

1. Locate a group to join. On the front page of Yahoo! Groups, you can browse the Groups directory or search for a group by topic.
2. Click on the Join This Group button on front page of any group.
3. If you are not signed in, you will be asked to enter your Yahoo! ID. If you do not have a Yahoo! ID, you can register by clicking on the Sign Up link.
4. Set your membership preferences. When you join, you can choose a profile you'd like to display to the group, select the email address at which you'd like to receive group messages, choose how you receive group messages, and more.

Join the mailing list only:

We highly recommend you join a group via the group page (above). However, if you are familiar with mailing lists, you may join only the mailing list for the group. If you choose this method, you will not have access to all of the group's web features (Photos, Files, Links, Polls, Calendar.) In addition you will not have access to the My Groups page, where you can easily manage all of your memberships and email messages.

To subscribe to a group's mailing list via email, send a blank email to:
groupname-subscribe@yahoogroups.com

Make sure to replace "groupname" with the actual name of the group (e.g., pastry_chefs-subscribe@yahoogroups.com).

You will receive a confirmation message. Just reply to this message and your subscription will be complete.
