Then you can afford to wait for the Release Announcement - like the
rest of us - Or if you really wanted to know the answer to all these
question, you wouldnt ask the questions@ list that was created for
beginners quetions, you would go search the archives of the developer
lists, & subscribe some. No subscribing a list doesnt mean you have
to run it, just that you keep yourself informed & dont need to ask
quaestions in advance of reality to the wrong list.
