Guy have corrected his google translated positions now "line" like that one i have pasted here was fully changed now.
Now that part is not "direct" translation and have corrected most eye hurting grammatical bugs and its quite OK.
From my side what i could offer is translation that would be readable for noobs i would give it my wife to read
and correcting it till she would invest into that ICO ...
And i also could put that announcement lets say on biggest polish forum.
