After a rather full-bodied discussion on another list, can somebody point me at resources that give the details behind, 1) implied copyright for public forums, 2) given copyright for forums, 3) any legal actions in regard to copyright and public forums. The discussion centered around just who is the owner of the copyright for messages on a list if no copyright information is given at the time of joining or the time of posting (list owner, server owner, original poster, all posters involved in the discussion) and just who owns the copyright for messages that have disclaimers like "all material is considered copyright the original poster" - including if a list owner or server owner can assume the copyright just by informing members when they join that they are giving up copyright. In today's litigious society (or at least the United States society), it would be nice to know just where things stand in these issues. Thanks.
