Align subscribe fields

For the life of mine can't understand how do I align these fields. The whole form behaves wierd when I try different options "float:" but can't make it stay in center. What am I to do to make it come up in the center of page?

Hi,
it's possible but all input fields must be inside new <div> with extra class
so probably you have to override default view of module.
Then will be easy to center also this object.
