We're not currently in need of Admins seeing as I think Humphry and I have things handled ourselves. Dragonboy has been allowed to be inactive as a courtesy to his past contributions. Besides, to be an Admin, one must first have rollback status, and only Fruipit currently meets that requirement.
Well now that you're back, I suppose we can finish up writing up all articles to a better standard? Articles for cast, crew, songs, books, and the film itself still haven't been touched upon as significantly as, for instance, those for characters.
Admins aren't meant to police the type of edits that occur on the Wiki. At its core, the job focuses on site maintenance, not being the all-knowing authority of content. If you see something that needs improvement, you should go ahead and make the change because, frankly, I don't consider myself to be the editor-in-charge. Your contributions are just as significant as my own.
Regarding your second point, the choice to allocate time to edit on other wikis is my prerogative, so it really isn't something with which you should concern yourself.
