Might be worth grabbing it and the keys before Adobe takes it down.
They released a press release saying they didn't want people without licences to use it :/
It's not like them to give away anything in my experience.
Definitely handy though. CS2 is perfectly good software, used it for years. There is a misconception that the newer software is somehow massively superior, sure it's better but most of the updates are aimed at advanced users.
