I don't know why, maybe it's just the order in which they were enumerated originarily, but where are gamma, delta, epsilon, zeta rewrite rules? :) V. -- Please note that I do not read the e-mail address used in the from field but I read vincenzo_ml at yahoo dot it Attenzione: non leggo l'indirizzo di posta usato nel campo from, ma leggo vincenzo_ml at yahoo dot it
