According to the user guide, the link to the moderator's name is to go to a profile page. Is there a way I can link it to one of my articles where I have a biography article about that particular moderator?
The profile would be their user page within Community Builder or JomSocial. You can set those up however you want. If you are not using one of those systems, then there really isn't anythig for you to link to.
