Hello, Yaron, I didn't find your e-mail address, so I'm posting it to the list. The link email-me on the site didn't help either. (It didn't do anything - I have Netscape Navigator 4.04) I think you should add: http://www.cs.technion.ac.il/~gil/pub/Hebrew/ too. Liran Zvibel http://www.math.tau.ac.il/~liranz/
