(with the usual apologies for cross-posting) Folks, as you may have noticed, our mailing list have recently become a vehicle for spammers. I just made a change to our subscription policy to try to curb this: from now on, all subscriptions will have to be approved by hand by the list admin (that is, myself). It's a little annoying but it's a sad necessity. ------------------------------------------------------- Riccardo (Jack) Lucchetti Dipartimento di Scienze Economiche e Sociali (DiSES) Università Politecnica delle Marche (formerly known as Università di Ancona) r.lucchetti(a)univpm.it http://www2.econ.univpm.it/servizi/hpp/lucchetti -------------------------------------------------------
