first of all, my regards to alex, way to go. this site is great for many reasons,yet i would like to point out just one: it gives a sight of math that very little people have. not me, i've been in love with maths ever since i learned that 1/3 is not 0.3333 or so at the age of six. anyway, it's interesting for me to see how someone can be so nice to post a site like this, in spite of the fact that you surely have to deal with the "i don't get it" messenges from people that are too stupid to live. really, you've won your wings.
