This site help's promote security and how to protect our own network's. We aren't hacker's for hire and most of us have spent years learning about Secuirty etc.

If you have a real interest to learn we will happily discuss ideas's etc etc. Post some of your reasearch or ideas you have.

Re Yahoo and Hotmail etc. They employ the best in the game so i doubt they have many security weaknesses so personally i wouldn't start there if your just starting out in security.

If you have a real interest have a look around and hopefully we can be help you on your way.

Good luck.
