[Slacker]

Ok I am wanting to learn for educational purposes, There is one site i want to play around and test this on but it is ran by my self. If any one is willing to teach me how to exploit weaknesses in a site it is greatly appreciated. I am wanting to learn incase my site is ever takin down when we get it up and running, like what to look for and what to make sure is not a vulnerable weakness
I am fairly educated and catch onto shit fairly quick so there wouldnt be any need to repeat your self over and over to me.
