I'm sorry to hear you're unhappy with the registration process for the WAXP. XPRIZE is an established non-profit with a well-documented history of over a dozen competitions in the last 20 years. We've been working closely with Australian Aid and the Tata Group, our sponsors, and we're in daily contact with Australian Aid staff. We're not a scam, and the Water Abundance XPRIZE is not a scam.
The reference to the Rules & Regulations in the Guidelines was an unfortunate error. Although the names are confusing, the Guidelines are the legal specification of the competition. The Competitor Agreement - the contract that governs your obligations and XPRIZE's obligations - includes the Guidelines. It does not include the Rules & Regulations.
We publish Rules & Regulations from time to time, and those will change during the competition. Sometimes they are published before registration ends, sometimes they are not. The first version of the Global Learning XPRIZE Rules & Regulations was released about a year after registration closed.
The Rules & Regulations are essentially the implementation details of the competition. So the Guidelines might say, for example, that teams must submit design documents by September 1. The Rules & Regulations might further explain that those design documents should be in PDF format, no longer than 10 pages, and uploaded to a certain file-sharing server with the team's username and password. That's not changing how the competition works, it's just filling in the details.
