When we have a button on a website for creating an account, should it say "sign up" or "signup"?

I see "sign up" in most places, but which is the correct one?

I have never seen 'signup'; could you provide a link to a place where it appears? –  user19148 Jun 20 '12 at 20:31
    
I really meant 'sign up', fixed it. –  Haralan Dobrev Jun 20 '12 at 20:32

It should be sign up, as that is the verb form (see definition 30). Signup (or sign-up) is a noun.

That pattern usually holds: log in (verb) vs. login (noun), sit up (verb) vs. situp (noun), etc.
