Please remember not to bite the newcomers. Far from newcomers being a horde of monolithic vandals, trolls, incompetent fools, and spammers, a 2006 essay indicated that newcomers wrote most of Wikipedia's content. That's a lot of content, and these people have taken the time to research and post excellent info which many editors (vandals in my humble opinion), have simply deleted later, because it was not written up to their standards or they felt like the info was not relevant, or they were not interested in it.
Please take the time to re-write instead of deleting another's content contribution. Thankyou and have a great day.
