Actually it's the opposite.  Every mail sent to this list is copyrighted
by default, with the sender owning the copyright.  The fact that you made
your work public does not imply that it is public domain.  That's not to
say you would have much luck enforcing a copyright on anything sent to
this list.

I don't have the law handy, but it explicitly states that to copyright a
work, that work must be completely original.  What that means is that you
can't copyright modificaitons to an existing circle file (like
act.wizard.c), but you can copyright a new file as long as you don't do
any cut-n-pasting from circle.
