Notification system!!
It seems that we need an automatic system that would send notifications of activity to the members of the group. Like in news lists on the web, this should be a choice that every member of the group can set. The choices could be something like this: 1) send me an email every time there is a new resource o discussion added to the group. 2) once a day send me an email with a summary of the group activity (if there is any). 3) once a week (Mondays) send me an email with a summary of the group activity.
This way we’ll know when there is something going on that we can check on the group’s webpage. jose
