set myspace to be public

1st of all, are you a member of under 16? If you are under 16, you cannot change it to public.

normally, you may change your profile to public by this way:

login, then edit profile, then account settings, then privacy, then "Profile Viewable By: everyone"

If you can't solve your problem, don't hesitate to contact myspace staff, they will help you out :)

Good luck!
