@rainbowdash4l has, without knowing it, pushed me to do a #duo contest that is open to the "public".

It's simple.
I have a number between 1-100 (both included), and the one who gets closest to the number win a duo call (0.2 DUO).
If one guess the correct number there will be an additional 0.3 DUO. This additional DUO for correct guess will go up if no-one guess the correct number, until one gets the correct number. That is potentially a lot of DUO.

This thread is not the actual contest, but an announcement.

The contest will, for now, be running on InLeo and there will be an announcement article (long form post) with details and template to the threads.
More details in the article, but if you don't come across that, just look for the tag #cmduo
