A Scooby-Doo fanfic (Sorry if u think its weird)

Hey peoples! I know this would be a weird fanfiction but I LOVE Scooby-Doo. (DON'T JUDGE ME!!) And I don't mean the stupid and bad animation one they show on cartoon network, I mean the older ones. Anyway, this is written from this girls POV who loves Mystery Incorperated. She only dreams of meeting them. One day she is involved in a mystery they're investigating and asks if she could help. They say yes, but then she asks to become apart of the gang. Will she become a permenant member?
