To add a user to your personal Ignore List while viewing a message:

1. Click the "Ignore User" link located on the left side of each message.
2. After clicking "Ignore User" you are shown a confirmation message.

You can also directly add members to your Ignore List by using the Settings page:

1. Click the "Message Boards Settings" link located in the upper-right side of any page on Message Boards. If you haven't signed in, you'll be prompted to do so.
2. Click the "Ignore Settings" tab on the left. Under the heading "Add one or more users to your list" enter the Yahoo! ID of the user you wish to ignore and click the "Add" button.
3. If the Yahoo! ID is valid, you receive a confirmation and see the user(s) in the list below. Finally, click the "Save" button to return to the Message Boards.

When you add a user to your Ignore List, you won't see any messages by that user on the message boards. All messages posted by users on your Ignore List are replaced by a message stating "you are ignoring this message."
