Maintaining a Team

Team maintenance in Nimbus has built in security provisions designed for larger businesses to support independent administration for different departments, such that departmental administration cannot fiddle with teams for other departments.  This is important to protect access to team specific documents (like the HR dept).  
Teams work such that any staff member with admin level access can administrate a team (i.e. add/remove staff). However, if that team adds another staff member with admin level access, that staff member becomes the new team administrator and you as an external admin loose the ability to maintain it, unless you also are part of the team.
The solution to maintaining a team that you may no longer have access to,  is to ask the new Team Admin to include you in the team - or ask them to make whatever changes are required.
