Is there a way of checking if a YouTube user exists?
could just try to request the username your looking into with the profile feed
http://gdata.youtube.com/feeds/api/users/username
should get a 404 with User not found in the body, if the user is not created.or a normal feed if they exist.
More info here http://code.google.com/apis/youtube/2.0/developers_guide_php.html#Profiles
That won't work for me, I need a Variable or something. It cannot be an error page.
I got it I'm just gonna use JQuery.
