Heh, now that I look at that thread, this is obviously not the forum that asked permission, since it is pixel-art related and not in Polish.
Zolthorg: I think general consensus of that thread was 'yeah, go for it' and nobody was against it. Then again, the conclusion (or lack thereof) of the old thread isn't really the point here.
Anywho, I'm sure someone's on top of this by now.
