so I agree that Ziemowit was bit snippy with the OP about the spelling but we all have our moments ;)
The point was that the OP used the letter á which doesn't exist at all in Polish.
If he wrote "Poźnan" or "Póznan", I wouldn't correct him.
who corrects me every time I speak Polish at a party while everyone else just talks to me
I wouldn't correct any foreigner talking in Polish. On the PF I occasionally correct those of whom I know they would welcome it. I have never been ridiculing any foreigner trying to use Polish. This is bad taste.
My remark
Correctness first, money later.
was just a kind of joke and the ;-) sign should have followed it. Sorry if anyone felt offended by this.
