JamesD28 I understand what you wish to imply. But I do believe we need to let the current challenge run for a few days (or a week) before incorporating any change or starting a new challenge to bring the odds in the favor of a completion.
Only through practical implementation and exchange of views can we arrive at tasks that are challenging as well as fall under reasonable efforts. So let this challenge remain open till the lucky ones appear and in the process, we can decide the parameters for a similar such challenge next time.
And I do wish to thank everyone who are trying against such high odds and sharing their views. Its helpful to prepare new challenges in the process.
