wooohuu! My first setup, just manage to get 'Bit-torrent' as a application in Mozilla!

...nice feelings when you accomplished something
Question 1: Is it possible to "resume" the files you're downloading through bit-torrent?
Question 2: It seems that everytime I change OS my ISP asking for my username and password before I can use the web, is that normal?
Question 3: I've tried to install Dom2 in the linux OS, I follow the instruction that came in the note, but somehow I must do something wrong or the instruction is incomplete. Can someone please post a more specific way how to install Dom2 on a Linux (mandrake) OS?
with best regards
