Q: Why are all the letters singed by someone called "SF"?
A: To make a long story short, a friend called me a nickname, a variation of that became a common username for me on various sites on the internet. An online friend started abbreviating it SF (even though that honestly is a poor abbreviation for it), and that stuck and I started commonly being referred to as SF in various places on the internet where real names aren't used (online games, various websites, etc.). Since this is an online thing, I decided to use my "online name" of SF.
Q: Why is there only one question in the FAQ?
A: Well, thanks to this question, now there are two, so your question is pointless. But mostly because it's relatively new and as questions become frequently asked, I'll add them here. If you have questions, there's a tab for that, or you see the "about" tab for other ways of contacting me.
