Final answer:
When citing an article from a discussion forum, include the full title in the subject line and use proper quotation marks and citations.
Step-by-step explanation:
When citing an article you found in a discussion forum, you should always include the full title of the article in the subject line of your post. This makes it easy for other students to search for the article. In your post, use quotation marks around any words you directly quote from the article, and credit the source of the quotation. Follow the formatting style guide assigned by your instructor, and include citations and reference pages for academic papers.
