A newsgroup has been created for the Panamerican Group. This discussion group utility allows you to collect and store comments on whatever themes you may want to explore. The email group allows any members to post a message or comment to all the other members at once, without having to worry about maintaining lists of everyone in the group. Profs can circulate lesson plans and materials, students can post comments and let the group in on any neat URLs pertinent to the course.
Profs can also post their lecture notes before or after the class, etc.
