As far as I know all the hasty pastry posts from a certain date (and I'd have to find that date it was added 'cause I don't know it off the top of my head - obviously not top priority in my head) are covered by Creative Commons License.

Edited to add the url I meant to post:

Frankly I've never understood Creative Commons despite having read it a dozen times.
I think there are situations where it is appropriate (a special sticky post in SOS forum comes to mind), and I think there are situations where it is not appropriate.
I would really dislike seeing mass copying of threads and posts. That's already happened here in the past on one forum and it involved a thread with mulitple posts from people who would never know that their words had been copied over here without their permission.
So, my personal opinion is that this matter be treated with extreme care and caution.
