Organize the list by "admin" or "bureaucrat" and find your username. If you are the founder of the wiki, you should have both permissions. Alternatively, you can use the API to retrieve your username as part of the wiki's meta info. Do not look at "staff" users as that term is used for paid Wikia employees, not local wiki admins; so you won't be included in that list. Well, unless you are actually Wikia staff; but then I don't think you would be posting here about it if you were. - Edit:

What is the domain for your wiki? Neither general internet searches nor the API return any results for "Extra400"; which indicates that the wiki doesn't exist.
