Hello Augusto,
you forwarded the following message concerning NOMS in Honolulu, US:
******* Register now for NOMS 2000 and join your colleagues in Honolulu, Hawaii from 10-14 April 2000 for the 2000 IEEE/IFIP Network Operations and Management Symposium. *******
Did NOMS ever pay the sponsorship fee for IFIP (or at least half of the fee if we would have to share it with IEEE)? They should do so because the event is a "symposium", i.e. a large one.
Best regards Otto
