Phew, it seems the slot is too fast to fill, still got the last spot waiting to @inspace if my entry is credited to the last spot!
Good luck to all participants!
It's a pity that I missed this contest. I didn't see the announcement in time, but I would have participated for sure. Next time, if such a contest is launched again, I will definitely take part. Besides, this particular contest requires only a number or a letter to participate. The rules are as simple as possible, that's why all the places were quickly taken by the participants.
