Oh man, I'm sorry to hear that. I know the Video Art Track people have always been responsive although they're probably not the people to contact for other panels. I would have loved to attend. Hopefully, I'll get to attend the OCRemix panel at Otakon next year.
VG4 will definitely make more appearances at Anime USA, Youmacon, and possibly MAGFest. Hope you can make it for those.
And big thanks for everything djp, these projects couldn't have been possible without the hard work of you and all of the remixers.
