Alexei Frounze's site has lots of great documents, but it's really slow. So I made a mirror, alexfru.sky.prohosting.com. (Sorry about all the ads :'( ) Anyways, I've uploaded all the files from alexfru.narod.ru (it took a LONG time to download them) so you can download them much faster. However, although I uploaded them there's a 404 error if you try to download them. So wait. Tomorrow, you should be able to download any file without any errors. (Note: I removed all the broken links I could find, but if you find any more once the entire site is working, probably tomorrow or the next day, tell me!)
