Mysql count columns of users, and group by modified date

There are 2 columns that I want data from. Basically I want to see new signups per day. Go easy on me, my first day with mysql (or any DB for that matter)

So far I have this

mysql> select created, count(id) from user group by created;
+---------------------+-----------+
| created             | count(id) |
+---------------------+-----------+
| 2009-05-27 00:58:56 |         1 | 
| 2009-05-27 01:27:30 |         1 | 
| 2009-05-27 02:35:37 |         1 | 
| 2009-05-27 02:58:56 |         1 | 
| 2009-05-27 03:36:03 |         1 | 
| 2009-05-27 03:38:03 |         1 | 
| 2009-05-27 03:48:16 |         1 | 
| 2009-05-27 03:51:37 |         1 | 

The output I would like is

+---------------------+----------------------+
| created             | user                 |
+---------------------+----------------------+
| 2009-05-27          | 10                   |
| 2009-05-28          | 13                   | 
| 2009-05-29          | 19                   | 

Any help is appreciated!

Thanks
