I was wondering: say I have a website where users discuss different articles and when a user wants to discuss a specific article, he/she will be able to link to that article and then say what they have to say.
Certainly, copying and pasting would violate the site's copyright but simply including a little link sounds like a legal alternative. Is it really? Or, technically that would still require me as the webmaster, or the user who posted it to request permission just for linking?
I know nobody would care because it only gives more traffic to the site but legally, would permission be needed?
Thanks in advance.
