To absure a right tone of messages and to avoid unuseful controversies or flames, the mailing list is moderated; it seems that who will not keep an admissible discussione tone, will breed too many controversies, will be bothersome for the greater part of other members, will be rebuked and, if necessary, removed from list.
Anyway it doesn't mean censorship, in fact the intention of moderators is absuring everybody the full freedom of expression and will be token measures only in the case of offensive messages, or non-respectful for one or more members, or in the case of messages that would be absolutely unfit to the subjects that mailing list should pursue.

In the case of a message considered unfit, the author will be invited by moderators to temper his terms or to keep a better tone; in the case of "reiteration of crime" :) the member will be removed from the list.

So the invite is to think two times before writing a polemical message and not to let other messages contents alter oneself, cause it won't help anyway.

It is important not to take moderators' place, but to signal them what you think not right or unfit to the mailing list; everybody can also freely say his opinion about moderators' work if he doesn't think it right, talking about it with moderators themselves in a private e-mail.

There are no other particural rules to be observed, anyway it is not recommended an excessive quoting of other members' interventions and an excessive prolixity of messages, while it is advisable to choose and put a right subject for oneself messages, in order to allow a more viable reading.
