IF YOU WISH TO RECEIVE ABSTRACTS OF FUTURE ARTICLES IN THE JOURNAL, PLEASE SUBSCRIBE TO THE JOURNAL, IF YOU HAVE NOT ALREADY DONE SO. You can subscribe by simply sending your full name and postal address in an email with subject `subscription' to tac@mta.ca. Subscription is free. There are two reasons for requiring a separate subscription to the journal. First, subscribers to one of the categories mailing list or the electronic journal may not be interested in the other. Secondly, while access to the journal is free and open over the Internet, it is obviously useful to have a base of known subscribers. You may rest assured that the subscription list will not be used externally.
