That's the exact same principal.

You name the category "Category: Characters made by XXXXX"

The only thing you need to write in the page are the sentence "This category should contain characters made by XXXXX." (if that creator has a page in the wiki you need to put his/her username between [ ]) and "Category:Characters by creator" between

There you have it
