There is no problem with fanfiction-related content on this wiki, as long as it is added to the proper destination. As bureaucrat of this wiki and team leader of MoviezWorldwide I mostly focus on the professional aspects of a community, despite all of our staff members having a past history of writing fanfictions. However as the years passed we focused more and more on fields of business like collecting dubs, uploading videos, managing social media channels, making statistics etc. Thus I agree with your suggestion.
As I've said previously, Mr. Jara is most likely very busy with his current projects and it makes not much sense to him if he is contacted about something which is rather unlikely to come. As those fanfictions are your project, it also makes more sense if you would contact him, as it was previously said as well.
Currently I don't have any time do so. If I would contact people or companies behind a franchise every time an user asks for that I won't have time to get other things done. The same is true for Mr. Jara, as one of his main tasks is creating and outlining franchises, rather than responding to fan questions about a franchise which is already dead. Such things are a waste of time for businesspeople. I've seen several cases in which some fans couldn't believe that a franchise was dead. Tenkai Knights is a very prominent example. There have been a lot efforts to keep the fandom alive, but to no avail. Some users even interpreted Spin Master's responses to their questions as a sign, that there will be another season. Soon five years have passed since the end of Tenkai Knights and still nothing has happened.
