Accidental IT Girl

That's me... I am the "IT Girl" for my company. But I hesitate to use the title IT because that means I might have some training instead of just learning by doing. "IT Girl" raises people's hopes and expectations. They think I might actually be able to fix their computer problems. And there's about an 80% chance that I can. But that leaves 20% broken. Someone told me to just go with being called "IT Girl" because everyone already thinks I am so I might as well claim the title. I like that. Think I can put that on my resume?
