I am first of all, Portuguese, from Portugal that is.
I am quite old, 32 in April, but still young enough to try to be up to date with this hacking stuff.
I am currently using 3 OS's well, 4 actually, Slackware, W2k W98 and FreeDOS.
I think you could be interested in something I found out not long ago, DDos for Windows, like in Shaft or something equivalent for windows.
So... Thats it,
If you need anything... Post
You can find me @ #hackers.pt @ DalNet
