The only reason for this would be that your account status is not "Active", so check on your "My Panel" page while logged in to your LuvFree account and check the upper-right corner section "Manage profile" to view your Profile status. If your profile is in "Approval" status, you will not be able to send messages until the LuvFree administration team approves and activates your account which takes between 2-12 hours. If your status is "Suspended", you can simply reactivate your profile yourself by clicking the "Activate profile" button. If your status is "Unconfirmed" you need to confirm your email address as soon as possible. For more information on profile statuses, take a look at section 2.10.
