I have two laptops: a G3 Lombard Powerbook and a Macbook Pro. I took a calculated gamble and purchased SpamSieve on the strength of the reviews I read about it. I installed it on the Macbook Pro and the results so far are mighty impressive. However, I use my Macbook Pro as a backup and for when I need some real power, e.g. when using Photoshop CS. My main workhorse is my G3 which I use for everything else, including my emails. I have a .MAC account which I use to synchronize the two computers.
My inquiry is simple: must I purchase a second copy of SpamSieve for my G3 or can I download a second copy and use the same registration details as on my Macbook Pro? I assume I must make a new purchase?
