What is crossposting and why should I not do it?
Crossposting is posting the same message to multiple newsgroups at the same time. It is considered poor netiquette to crosspost even if the message is on charter/on-topic for the selected newsgroups. If there is something that should be posted to multiple newsgroups, then the message should be sent to each newsgroup one at a time instead of posting to all of them at once.
