well, i made a glance... tutorial gives most general knowlege about asm, coding in DOS and Windows, it is good for start. You could add some words about coding for bare boards (replacing BIOS), for Linux systems and about pure assembler OSes of Menuet family - at least general info. i think at fasm forum you may find some experts on these questions who can help you
also tutorial is in polish language, i do not think a lot of men will use its translation to learn assembly, more: if you use different language you loose some advantage of wiki: you cannot participate
but it is good for polish users: we still think faster and better in own languages, so, who understands polish well he may look at that tutorial to get common imagination, understand how does it all works and start. translation is also a piece of work
in any case you made a large good work!
regards!
