   Thanks a lot everybody, a stone fell off my heart.

About the RKM L's D's. My question actually originated in the above passage.
And it mentions nothing about the Process struture :) It just, merely,
summarizes (what we all know), why requesters have a right to exists. Perhaps
my edition has a bug. (It has least one more, since half of a listing is
missing, about menus I think)...
I'm sorry about my harsh tone in my previous letter, but I just felt lost,
panicked and in every way irritated :)
