- I don't know why more people register now, as they are all guaranteed
- upgrades to 2.0 for free, and it would help you get 2.0 out faster, and
- more stable if you had the money for such purchases. I saw many requests
- for Executor cracks on the Usenet. I just wanted to punch something.

- If I get a ZIP drive soon, and figure out how to dump out 2048 bytes
- right off a hard drive like you mentioned, I'll help.
