I am the originator and a workspace coordinator for a number of beehiveonline workspaces/groups. I have been able to administer these groups in the past. However, this week I no longer seem to have access to several of the groups. The groups that I have lost access to are:
firstname.lastname@example.org is the manager of the groups and can add you to the management app to allow you to add users. Your email address has to be entered into the Manager's Email filed - separated by a comma if there are several "Managers".
This wil allow you to add the users you need - you still show as a coordinator of the Workspaces you mentioned.
