Hi there, I just knew about this site and I'm so excited to sign up so I can share you the character I created and the story. But there's one thing I don't understand and I need to know. This is what I read in the Rule page:

You are allowed to do cross overs but do not do them unless given permission by the user of the article or universe you wish to cross over with.

My fanfiction is a crossover, but I don't understand what does that mean, can you tell me what should I do exactly, please?
