I think I'm the first one to post my fluency in American Sign Language (ASL)! I'm working on my minor in ASL, and have interacted with deaf people for many hours. I'm taking advanced ASL this semester, and then Finger Spelling, where you spell out every word using letters, not signs.
Edited to clarify that I was the first to post about ASL. As Rudey mentioned, I am not the only person on here to know ASL!
