Editing the join and login form

Hi,

Is there a way to edit the structure of the join form?

Right now it display all fields in a row, and I want to split those in 2 rows. 

What about the login form, is there a page, or only the click and show? I tried to duplicate the join.php but I receive a no page found when trying to call in a browser.

For the join frm. I do not know of a way to split it into multiple coumns, but you can split it into multiple pages (helps knock out a lot of spammers also). If you look on the top block of each section in the profile fields builder, see image.
