To fully utilize MetaX you will need to purchase it for $9.95. Before it is
registered, you can read the tags in a file and use all the search options to find
the tags from sources on the internet (see Searching for Information)
but it will not write the tags out to the file.
To get your registration code, go to the MetaX home page and click on the Buy Now button.
You will get a username and registration code via email and can use that in Help->Register.
