I see in the docs that you can save additional user data using addJSONObject() followed by createUser(). But I'm wanting to allow players to specify their own nickname that will be associated with their user account (which will be under their Facebook user ID), and I want to store this as "additional data" associated with the user's account.
Is there a way to add or modify this additional information after the user's account has already been created?
Judging from the fact that you must specify a collection, am I right in assuming this means the data can be accessed and modified like any JSON document? Please help me understand how this works. Thanks!
