Discussion boards in LBS Hub are related to the club(s) that you are a member of. Unlike Portal, there is no 'General' discussion board that everyone can post in, so for the moment the general Campus Community discussion will remain there. To set your preferences for what you receive emails about, go to Clubs > My Clubs. Click on the club, then click on the Club Settings button. Select the Notifications option from the menu and check the boxes for the acvtitites you would like to receive notifications for.
