This plugin has been written to insert an Author introduction to each Archive, based on their User information, including their bio etc.
This plugin gives you the ability to add a Author introduction to each Archive. No editing of themes is required to use the plugin and a default layout is set up on install. Play with the html layout until you get exactly what you want. A number of tags are provided to give you access to the Author data [authorID], [authorDisplayName], [authoremail], [authorURL], [authorPostsLink], [authorGravatar] and [authorBio] also optionally you can use php if you are an advanced user.
Tags are evaluated first, then php before the results are returned.
