Hi I noticed the added copyright rule. Could you add there a link to some site that explains copyright restrictions (e.g. how long is copyright protection etc)? Also, some material is copyrighted in some countries but not in others, and that may cause confusion and ambiguity about the application of the rule. For example, I just found an official looking site with Orwell's 1984 which I thought was copy-righted, but from that site it seems that it isn't, at least not everywhere.
