It is actually just one letter, but because new genuine users might read the OP and confuse themselves if they does not know about it already, you should do it immediately.
That highlighted zero (0) needs to be changed to one (1) according to the new changes.
That's still ok, new genuine user will not be having 30 activity and old newbie confusing itself means that user is not reading things properly.
(Whatever Theymos written that need to be taken, no need to getting confused with anybody else.)
Sad thing is that no "newbie" responded to this challenge, even I posted about this challenge in "Beginners and Help" board in one of my post and almost a week passed since this challenge is opened.
Not sure, whether it is the implicit nod from them that they know they are in shitposting and in no mood to change.
