At the bottom of each email I see links to 'Messages', 'Links', 'Databases' and other email options. When can I use these?

When Mailing-List-Only members click on these links they will be taken to the dalesfhs website Home page. If you want to explore the website further you will have to register (Illustrated Guide (IG RYA) with Yahoo and set up a Yahoo ID and password.

Once you have set up your Yahoo ID and password you can upgrade to Full membership. Please see the Question How do I upgrade from Mailing-List-Only to Full member? and its accompanying Illustrated Guide (IG UFM). Since you are already a Mailing-List-Only member of the Forum, this is a simpler method than clicking the Join this Group button offered on the dalesfhs website.
