UPDATE, Y'ALL!
@fulltimegeek & @heimindanger: OH MY GOSH! OH MY GOSH! I don't know why it finally worked but it did.
I got to thinking and realized @quitefrankly has been able to upload to D-Tube from his location so I signed into the show's account and gave it a reluctant but determined push. It didn't work on Firefox but I went ahead and tried Chrome again and FRICKIN' PRESTO! The odd thing was that the "submit" button wasn't looking clickable on Chrome either but I took a swipe at it and it actually worked this time!! You can't possibly imagine my delight but it looked a little like this:
After I got it to go through for QF, I logged into my own account and repeated the process and it worked for ME, TOO!! I would shout a hearty "WTAF" in a vaguely skyward direction but honestly, I don't think I want the answer so I'm just keeping it to myself. If anyone asks, I never said anything to that effect, okay? Cool.
Anyway, everyone. I suppose the moral of this story is, if at first you don't succeed, complain loudly (and publicly) and then try try again. With just a little stick to-itness, everything will eventually work out in some totally nonsensical way.
Congrats on getting it working man!
Just one step closer to world domination!
