SM (not S&M!) is one of my passions, but since publicly discussing it embarrasses me significantly (which you would already know if you correctly determined the two-digit number in my username to be my year of birth), I have developed a shorthand system to address that embarrassment. If you wish to talk to me about SM, you must use this shorthand system.
After discovering the Inkscape SVG editor, I've been pretty active on the Commons, uploading new vector images, mostly of flags. My user page on the Commons has a gallery of those flags that I have contributed to date. I now track national flags on this page.
