I am using this to generate a bunch of data I then want to export and use to test a Wordpress migrator I am making for a forum software.

After generating 15 users, I made some posts and comments (in that order).
Looking at the database, the user_id column of all created comments is 0, and the author is a random name.
I expected these to be pulled from a random pre-existing user.

Is it possible to get this added as an option?
