YeeeS!!! You are a genius with eagle's eyes!

I've suspected from the beginning something like this has to be
there... And I really tried to find this before sending this. But,
as a matter of fact I didn't even try this "plain" or rather "raw",
because I've somehow thought "raw" is just plain text, so the same
only without html tags!? So, now I know, and it's enough to me. But,
... maybe it should be on this "complex" page as well?

Thanks very much,
Jarek P.

PS: I hope eagles can see in English at least the same as in Polish,
and more than I can see in my dictionary now!
