The plugin provides a widget called "Linkify Tags" as well as a template tag, c2c_linkify_tags(), which allow you to easily specify tags to list and how to list them. Tags are specified by either ID or slug. See other parts of the documentation for example usage and capabilities.

What happens if I tell it to list something that I have mistyped, haven't created yet, or have deleted?

If a given ID/slug doesn't match up with an existing tag then that item is ignored without error.

How do I get items to appear as a list (using HTML tags)?

Whether you use the template tag or the widget, specify the following information for the appropriate fields/arguments:

Before text: <ul><li> (or <ol><li>) After text: </li></ul> (or </li></ol>) Between tags: </li><li>

Does this plugin have unit tests?

Yes. The tests are not packaged in the release .zip file or included in plugins.svn.wordpress.org, but can be found in the plugin's GitHub repository.
