i want to learn how to hack a forum/website

and i mean shut it down of course

Lol, why all the hostility? =)
Besides, this is the "dot" hack section. (It's a videogame)

And that's pretty illegal stuff, so I'd say no.
Locking this topic. Try contacting someone in private (not necesarily on this site) if you really want to know because I doubt many forums would allow topics on that subject. For obvious reasons. lol
