Two years ago I published a post on the Pflaum Gospel Weeklies. While the latter are available for paying subscribers only, the monthly newsletter designed to support the Gospel Weeklies is freely available. This newsletter contains a number of valuable features:
Saint of the month: Each month a different saint is highlighted in a brief article with suggestions of activities; Teacher tips; suggestions of activities; Parent Tips; Catechist to Catechist (advice for catechists).
Two issues of the newsletters (the previous newsletter and the current one) are availalbe online at http://www.pflaum.com/pgwnewsletter/ . You can also subscribe to receive the newsletter: http://www.pflaum.com/forms/pgw_signup1.php .
