You must cite the source and if possible the author, which are usually at the bottom of the article being copied. Often, I will add a small disclaimer at the bottom of the article:
"Reproduced under the Fair Dealings provisions of the Copyright Act." This is implied under a site like this, but it doesn't hurt to put it there.
Bruce Monkouse is right- slanderous, libellous, offensive material gets yanked on sight. If anybody spots material that falls into that category, hit the Report to Mod button.
As for the T & C's... still trying to get the time to finish them off. I'm also taking suggestions on them via PM.
Here is the actual text of the relevant portion of the Copyright Act:
PART III INFRINGEMENT OF COPYRIGHT AND MORAL RIGHTS AND EXCEPTIONS TO INFRINGEMENT
Criticism or review
29.1 Fair dealing for the purpose of criticism or review does not infringe copyright if the following are mentioned:
(a) the source; and
(b) if given in the source, the name of the
(i) author, in the case of a work,
(ii) performer, in the case of a performer's performance,
(iii) maker, in the case of a sound recording, or
