On my protected content pages, there is a register link.

On my protected content pages, there is a register link. I want to remove this link. I only want admins to be able to add a new user. How can I remove this link? Thank you!

Also - see attached screenshot, the "Remember Me" checbox should be displayed inline with the text. I cant get it to float:left or display:inline using my browsers Inspect Element - can you help? Thanks!!!
