11. Core Offline Team CERN financial situation is very serious
Quotas for personnel (PJAS, FELL…) are reducing
Staffing of the core team may become critical
The collaborating institutions may have to help with core offline
Keeping people at CERN
Providing people at their site to
A proposal will be presented to the MB this week
