Dear chive,
Would you be willing to put a prize to this man card challenge? I believe it would inspire loyal Chivers to try and be more than they currently are.
Now, It may take a lifetime to get proof of completion should someone decide to undertake the challenge, or there may already be a person with a lifetime of proof. Either way a man of that stature should be recognized for his achievements.
I also understand that some of the man card challenges are extremely dangerous. I'll understand if you can't sponsor the challenge formally. Although, I don't think there would be any harm in tossing such an established man a Chive Tee and possibly an exclusive chive photo album on your home page.
I hope you will consider this.
