function Send-TwitterFriendships_Create {
<#
.SYNOPSIS
    Follow, search, and get users

.DESCRIPTION
    POST friendships/create
    
    Allows the authenticating user to follow (friend) the user specified in the ID parameter.
    
    Returns the followed user when successful. Returns a string describing the failure condition when unsuccessful. If the user is already friends with the user a HTTP 403 may be returned, though for performance reasons this method may also return a HTTP 200 OK message even if the follow relationship already exists.
    
    Actions taken in this method are asynchronous. Changes will be eventually consistent.

.PARAMETER screen_name
    The screen name of the user to follow.

.PARAMETER user_id
    The ID of the user to follow.

.PARAMETER follow
    Enable notifications for the target user.
