Forum Facebook Connect Registration and Maximum Username Length
 

Does the Maximum Username Length value which is set in AdminCP -> Settings -> Options -> User Registration Options apply to users who register for the forum using their Facebook accounts or is that username length only applicable to those who manually type in their username at account creation time?

My forum has Facebook Auto Registration on where a user's account is automatically created when they sign in via Facebook and am wondering if the maximum username length value is respected or ignored.

Thank you.
