As for me, I kind of knew about the site since it formed (I remember the big "omgsmwcentralishere!!11" on Acmlm's) but never really joined because I wasn't really big into SMW at the time. As soon as I started back into it, I joined here, and ... here I am. It wasn't too bad to get started because I knew 75% of the people here already heh.
I wasnted to learn moe about hacking. I found a linik to the site's FAQ from google. I soaked up the FAQ like a sponge and then decided to join as a token of thanks to the site that taught me everything I know.
(Copied and pasted from Luigi1000's "The Truth" thread)
I chose the name "Meister Waluigi" because I was intending to just ask a question and then leave, but then I announced Super Mario Infinity, and before I know it, I'm a regular and well-known SMWC member.
I joined before the wipe. My name was LuigivsKoopa. And then, idiots attacked the site and banned me. But meh, who cared...
I'm done hacking SMW and SMK. Focusing on let's plays.
