hi
i'm trying to do a remote validation on an email field just like the
Marketo sign-up form one!
I'm not a programmer (don't know json too) and i don't exactly know
what to put in my "email.php" file (which does the actual check). At
the moment it just does a normal php check therefore nothin' happens.
Could anyone give me some clue or some good link to read from?

Thanks
Vitto
