Ask HN: legality of re-using publicly posted material
I recently set up a site which collates After Effects expressions and scripts (http://xscriptorium.com). At the time of building I conceived only of one scenario: the person submitting an expression is also the author of that expression. As it turns out, the community has come up with another scenario: posting expressions that were written by others. Now, that obviously makes this site a lot more useful when it comes to collating this content but I'm wondering what the copyright and etiquette issues are? A lot of this will, I guess, revolve around where these expressions are sourced - a lot of the time expressions are posted on the After Effects mailing list, in answer to requests for a particular expression.<p>So now I'm wondering what I should do? Is it legal?<p>Any feedback would be appreciated.
