What forum for selling LightSpace PRO calibration software?

I am closing my post production business and want to sell the license for Light Illusion LightSpace CMS PRO Professional Calibration Software. Any suggestion for where to list this? I'm having trouble finding a post production forum.
Thank you!

Hi Michael,
We don't need lightspace but I would be interested in a 2nd hand good condition colorimetry research cr-250 or cr-250-rh or perhaps a Photo Research pr-655 probe if you have one of those for sale as well.
Cheers,
Scott

Sorry for late reply, Scott.
I already sold my Klein K10-A.
