Citing articles

Okay, this guy doesn't know how to cite articles. It's not immediately obvious, but in at least some of his postings, he starts with a few sentences, and then appends an entire article that has been cut and pasted from another source. Nothing wrong with cutting and pasting an article, provided that permission is given and the proper attributations are included. Still, a good writer should make it clear that he is citing someone else's work, and should clearly delineate his own writings from the quoted section.
