I think that the big problem with the LPSG social groups is that they are not set up to generate subscriptions in the way that the message boards are. When you join a group you are not automatically subscribed to receive notice on your control panel of new postings within that group, and when you post in a discussion within a group you are not automatically subscribed to receive notice of new additions to that discussion. One can add subscriptions by using the "Group Tools" link on each group page. I have found it expedient to add a subscription to each of the groups to which I belong, but not to discussions within groups, as that clutters up my control panel needlessly. I will make a suggestion on this matter in the "Suggestions" forum.
