Need Help write MySQL query

I am having problem to write MySQL query to get data from 2 tables in the same database - one of them is Jomsocial table and the other is Joomla table) and hope to get some help from our friends here.

First table

jml_community_users

userid
points

Second table

jml_users

userid
name


I like to get the name and points of each member since 01/01/2012. I was trying to use Straight Join but having problems and also have problem with the date as well. I appreciate for any help you can spare. Thanks a lot.

 

SELECT
    u.userid,
    cu.points
FROM
    jml_users AS u LEFT JOIN jml_community_users AS cu ON u.userid = cu.userid
WHERE
    DATE(u.registerDate) >= DATE('2012-01-01')

Code (markup):

 

Thank you!
