Integrate Ajax Chat to Open Cart 1.5.x

  • Please help!

    I need someone to integrate this Ajax chat to opencart website.

    I will give 1 year FREE web hosting to the one who could help me with this.

    Actually all I need is something that will activate or make  this chat visible  whenever an account is logged in to opencart.

    only that…I dont know how to detect in the system whether the current visitor of the website is logged in to their account or not.

    Please someone help me….

    Thank you
