I found a site recently that was made primarily of mailing list posts. The home page of the site was categorized into sections such as "How to make a widget", "How to serve a widget", etc. When clicking on those links, it took you to another page on the site that had an entire thread copied (quotes, email headers, everything) with a conversation that accurately detailed the topic.
It seemed to be a very good resource. But I'm wondering whether or not this is okay for them to do from a copyright standpoint. If they received permission from the mailing list participants it would seem to not be a problem. But if they didn't, is it still okay? Are mailing list posts considered public or fair-use when republishing, or is owner permission still required?
Now that I think about it, I've seen posts "archived" in this fashion all over the place, just not in the organized way that this site had them.
Interesting, are the posts from UseNet or something?
I can't tell by looking at the posts if they are from a newsgroup or from a discussion mailing list, but such a mailing list would be functionally similar to a newsgroup that I'm not sure if that would be an important distinction.
If the policies are well defined it is not a problem.
Where would these policies be defined? By the poster of the message, or the charter of newsgroup/mailing list?
