The old database of this site was never backed up, hence all user accounts and associated contacts were lost. I highly recommend to the administrator(s) of this network that you back up a CSV file of group members. In the event a server change occurs, a backup can be uploaded, saving current members the trouble of re-registering or their connections.
In the meantime if someone can tell me how to create a group and why there are no categories to choose from I will be very encourage.
Peace
