First off, if you are going to keep it, don't put it right next to "exit" and also where "resume game" would usually be. Secondly, why the hell would anyone actually want to unregister?

Unregistering is good for moving your registration between copies of CC. When you unregister your key is valid to be registered again.
It should be kept, but not in so much of a prevalent position, maybe it should be moved to the bottom right corner of the screen.

I think this is possible through .ini modding to move it, but I also think would have to be readjusted as per the resolution in use, to put it in the corner.
I'll give it a try.
Heh, I like how Data simply admits he's nagging people into buying CC on the 'register now' splash screen shown when unregistered players try to exit, on the main menu .ini file's code.

Okay, apparently, if I'm not missing something here, that is the one and only menu button that isn't moddable in regard to it's position. What a bother.
Well, I tried. That verb describing what I did could be scrambled into an adjective describing me presently, so I'll be giving up and going to bed now.

Did you try to exit and accidentally unregister?

I've had to unregister/reregister plenty of times, like when you want to bring your copy of CC to a buddies house for four player ownage on the HDTV.
Also when moving computers you need to do that as well.

Good to let your friends play it when you aren't at home for a few days or just don't feel like playing it for a while.

It might need to be moved slightly but it's got it's uses.

it also provides easy reference to your key and doesnt just unregister you off the bat.

I get new computers all the time, and the unregister button has proved to be a very useful button. If I didn't have that button I'd either have to re-buy cc each computer I got, or email data each time (I still have to when I forget to click it before tossing ye old computer out the window).

Sorry, I forgot about that; yeah I've been using that lately. I was thinking about like 3 years ago when posted this: when I used to not read that and ask data like a retard.
