I have to register again, will my identity and other information stay secure and hidden?

Yes your identity will stay hidden and secure, but if you wish you can register with any name basically, we just need an email address of you to be able to contact you if you win (at that point we'll also need to know where to ship the seeds once we receive your payment). We suggest you use a user name that is different from the one you use in forums - this way you'll keep things extra safe for yourself too.
