Hey Roan. Welcome back. Please excuse the mess. I'll be bringing professional cleaners next year. :hrm:
Sean gave Netrep to XeroCreative, since he wouldn't have time to develop for it anymore. Deck Studio and RONIN are out there, now, too, until someone decides to continue developing for them. He provided the source codes for download right before he had to shut ccgtoolkit.com down. Other than that, I see him on Facebook and Twitter a lot, so he's still around, just not playing Yu-Gi-Oh much anymore.
