The last anime I watched was Hetalia but I finished it almost 4 months ago LOL.
I have disabled the article comments so that any joining users will go to the forum to discuss things.
When new users join I am thinking about getting ambassadors (will go to wikis like Test Wiki and Fanfiction wiki to ask for partnership), adminmentors (like admins but less) and rollback users (I really don't know what they can do but they can contribute to the wiki more). Also, there is to be 3 admins at all times with the Wiki at this size (1 founder, 2 locals) and more will be added as the site grows. See the Administrators page and also see the Style Manual.
