AOB:

• New protocol (AMS) enabled and enforced in APEL to post accounting report before it was STOMP (Oxana). Erik confirmed that SGAS used it since few months. The probe checking the consistency between APEL and SGAS  is fine(sure ?).

1st FitSM discussion:

• We have extended our knowledge with plenty of new acronyms  
• Having NT1 FitSM certified is not requested by WLCG. New communities might request it 
• Some part of FitSM are relevant for NT1:
  • Service catalog, portofolio SLAs and support channel for possible new communities
