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
