1. All posted articles and other media releases must respect the fair use rule. Unless you have explicit permission from the author(s) or the work is in public domain, it is not ok to post full articles or other media releases.

4. Lastly, the source must be credited, preferably with a link to the article in question. If you cannot remember the link but you can remember the name of the publication, mention just the name of the publication. If you cannot remember where you have the information from, state that the source is unknown.
