Adding a signature to my forum posts

How do I add a signature to my forum posts?

I feel that this "Cult of the New" seems to encourage: compile a collection of mechanisms, toss in some pretty minis and cardboard chunks, slather on some nice artwork and a passable theme, then throw it over the fence to people with money -- it's sales that matter, after all, not immersion... That, to my mind anyway, is a Frankenstein model: it creates a body without a soul. And perhaps worse... it deadens the tastebuds of new gamers so that they cannot even recognize a wonderful new flavor of game when it actually comes along. --Jim Felli

When someone tells you how to add that as your signature, they need to tell me how to hide all signatures. That's a god damned novel.
