Don't ask so that we don't have to answer. Please. No-one reads this stuff anyway.
How do I create my own user account?
When you add an offer for the first time, an account is automagically created for you. You don't need an account for anything else. So don't ask.
How can I contact you?
You can't. If you've got something to say, say it to the rest of the world (through twitter or something). If someone's listening, it's not us. We don't like customers. Besides, you're not even our customer! Or you'd have to pay us. A lot.
