I was reminded of this game by this delightful post.
There are two ways to do it: name-specific, and "OC".
I'll start with my name. Here's how you do it.
-------------
Step 1: Pick a fandom. The larger and wankier, the better.
Step 2: Go to fanfiction.net and choose your fandom.
Step 3: Search within that category using your first name OR "OC" OR "original character".
Step 4: Post the results!

Care to guess which fandom we're going to do first?
You probably guessed correctly.
