                        string NEW-EMAIL set this to change the email address. This is only respected on calls using update_existing or when passed to listUpdateMember(). Required to change via listBatchSubscribe() - EMAIL takes precedence on other calls, though either will work.
                        array GROUPINGS Set Interest Groups by Grouping. Each element in this array should be an array containing the "groups" parameter which contains a comma delimited list of Interest Groups to add. Commas in Interest Group names should be escaped with a backslash. ie, "," =&gt; "\," and either an "id" or "name" parameter to specify the Grouping - get from listInterestGroupings()
                        string OPTIN_IP Set the Opt-in IP field. <em>Abusing this may cause your account to be suspended.</em> We do validate this and it must not be a private IP address.
                        string OPTIN_TIME Set the Opt-in Time field. <em>Abusing this may cause your account to be suspended.</em> We do validate this and it must be a valid date. Use  - 24 hour format in <strong>GMT</strong>, eg "2013-12-30 20:30:00" to be safe. Generally, though, anything strtotime() understands we'll understand - <a href="http://us2.php.net/strtotime" target="_blank">http://us2.php.net/strtotime</a>
                        array MC_LOCATION Set the member's geographic location. By default if this merge field exists, we'll update using the optin_ip if it exists. If the array contains LATITUDE and LONGITUDE keys, they will be used. NOTE - this will slow down each subscribe call a bit, especially for lat/lng pairs in sparsely populated areas. Currently our automated background processes can and will overwrite this based on opens and clicks.
                        string MC_LANGUAGE Set the member's language preference. Supported codes are fully case-sensitive and can be found <a href="http://kb.mailchimp.com/article/can-i-see-what-languages-my-subscribers-use#code" target="_new">here</a>.
                        array MC_NOTES Add, update, or delete notes associated with a member. The array must contain either a "note" key (the note to set) or an "id" key (the note id to modify). If the "id" key exists and is valid, an "update" key may be set to "append" (default), "prepend", "replace", or "delete" to handle how we should update existing notes. If a "note" key is passed and the "id" key is not passed or is not valid, a new note will be added. "delete", obviously, will only work with a valid "id" - passing that along with "note" and an invalid "id" is wrong and will be ignored. If this is not an array, it will silently be ignored.
                        
                        <strong>Handling Field Data Types</strong> - most fields you can just pass a string and all is well. For some, though, that is not the case...
                        Field values should be formatted as follows:
                        string address For the string version of an Address, the fields should be delimited by <strong>2</strong> spaces. Address 2 can be skipped. The Country should be a 2 character ISO-3166-1 code and will default to your default country if not set
                        array address For the array version of an Address, the requirements for Address 2 and Country are the same as with the string version. Then simply pass us an array with the keys <strong>addr1</strong>, <strong>addr2</strong>, <strong>city</strong>, <strong>state</strong>, <strong>zip</strong>, <strong>country</strong> and appropriate values for each
                        
                        string birthday the month and day of birth, passed as MM/DD
                        array birthday the month and day of birth, passed in an array using the keys <strong>month</strong> and <strong>day</strong>
    
                        string date use YYYY-MM-DD to be safe. Generally, though, anything strtotime() understands we'll understand - <a href="http://us2.php.net/strtotime" target="_blank">http://us2.php.net/strtotime</a>
                        string dropdown can be a normal string - we <em>will</em> validate that the value is a valid option
                        string image must be a valid, existing url. we <em>will</em> check its existence
                        string multi_choice can be a normal string - we <em>will</em> validate that the value is a valid option
                        double number pass in a valid number - anything else will turn in to zero (0). Note, this will be rounded to 2 decimal places
                        string phone If your account has the US Phone numbers option set, this <em>must</em> be in the form of NPA-NXX-LINE (404-555-1212). If not, we assume an International number and will simply set the field with what ever number is passed in.
                        string website This is a standard string, but we <em>will</em> verify that it looks like a valid URL
                        string zip A U.S. zip code. We'll validate this is a 4 or 5 digit number.
