rawr,

There are a couple avenues you can use to get through 5. I will try my best to explain without giving the aswers out directly.

One answer is to use telnet, however you need to use the proper port for http. If you are behind a firewall that you cannot change settings on, then the telnet method may not work correctly.

Another answer is to use JavaScript. you can wite a string in the URL to send you an email of the password. (hint: if you can use POST, then you can use GET or vise-versa)

I hope that helps you enough to see the light
