In order to insert a translation from Spanish normally, you need to do the following. Paste your article into the page on Wikia first, and then copy your text from Wikipedia and paste it again. Then the text will be inserted normally.
I removed your trivia item about Callisto/Artemis because I think it is too speculative to appear in an article. However, this is the perfect kind of topic for a blog post. You can try to get a discussion going and see what others think about your idea.
I recently removed some edits you made to the article on Hermes where you were speculating about his fate and the Twilight of the Gods. We can definitely have those kinds of discussions but they should be done on the Talk pages rather than in the articles. Every article has a Talk page that you can access from the drop down menu beside the Edit button.
