@Tytanowy Janusz CONGRATULATIONS YOU'VE MADE IT!!!
I have nothing else to do but look for a charity organization and fulfill my commitment ...
Thank you. Take your time

choose wisely.
As a person who just finished challenge i can nominate another member. But I've decided to leave this spot as empty for others. I've created this topic for community. I've nominated once, i was nominated once now its time for you to have fun.
And of course big congratulations for Tytanowy Janusz
I wish I am so much merit away from Legendary, and I have not enough time to post such good quality posts as both of you to deserve merit's
Thank you. Well you can always challenge someone. There are 2 free spots. And I've added 2 updates so now you can challenge someone to earn fixed amount of merits (f.e. 20)
Update:
Most of the feedback I get is about that this challenge sounds fun but only few will have opportunity to take part in. I thought about letting nominated person nominate up to 2 users. But that way after 10 round I'll have to mange 1000 challenges. That's why I came up with an idea that I will open 3 spots for 3 active challenges per week. If you see empty spot that means that its free and will be taken by first challenge posted. You can challenge anyone. New spot will be realised if someone won't nominate new user on time.
Update 2.0 :
From now on you can challenge other member to gain certain amount of merits (f.e. 20). But if there will be more thrown challenges than empty spots priority goes to rank up challenges.
