Misleading method parameters

[NFGomes]

The signature of the method

public static string Create(AuthenticationDetails auth, string clientID, string title, string unsubscribePage, bool confirmedOptIn, string confirmationSuccessPage, UnsubscribeSetting unsubscribeSetting)

on the List class has confirmedOptIn as one of the properties, this is some what misleading since when set to true you expect the list to be created with the recipients already confirmed but no, setting it to true means that the recipients need to confirm their subscription, setting confirmedOptIn to false creates the list with the recipients already confirmed.

In my opinion this can cause some confusion and changing it's name to confirmOptIn would help clearing some confusion.
