Your candidate will soon be added to the MB subpage.
Three days after the proposal has been made, if the character has been approved, you may post the writeup (the text to be posted on the trope page itself) on the thread and send it to the drafts page.
The number of upvotes must outnumber the downvotes by at least five for the character to be considered "approved". After the proposal, there will be a 72-hour discussion and voting period, where people may ask questions and vote on the candidate.
An EP is not outright required, but please be mindful that if a post becomes too clunky and unorganized, it can be very hard for other people to follow.
