My real name is Samantha. :D My great-aunt used to spell it Sammi instead of Sammie, if I recall correctly.
I'm sort of irritated, though, becuase there's another Sammi on SPPF, so sometimes I get mixed up with her. It's irritating. I get enough of it offline. *sigh*
Every once in awhile, I debate changing it to another name from my characters (I write), but... eh. On one hand, the Sammi issue is annoying, but on the other, I don't have a really good name in mind.
