I appreciate the answer to my CSS validation question. Thank you very much.
Now please clarify for Donation purposes:
Who developed WU-graphs?
I had Email contacts with Rodamir Luza and I see here a person called Radek answering my css querry.
Now who is the programmer?
Please appologize my confusion.
Radek is in Czech language often used as "short form" for Radomir.
Something like Mick, Mickey, Mike, ... v.s. Michael.
BTW: My exact name is Radomír Luža but because english don't use letters as í, ž, č, ř, á..... I'm using i, z, c, r, a...etc. (without diacritics) It is less confusing for peoples without Czech keyboard.
