To your edit, no, they are not saved. I did fail to mention in my last comment, you can save a small channel trailer for now, till I run out of 500gigs of disk space on the server and have to solve that problem too, but users are limited to 500mb uploads which means just a clip, teaser, trailer, commercial spot type thing to explain your channel to browsing viewers.
The goal is to move storage to de-cent IPFS systems via Hive ecosystems partner offerings or something like StorJ if I have to reach outside the Hive chain/tokenomics to make it possible.
Great stuff, @sircork! A wonderful addition to the HIVE Project!
Thank you very much! I've been burning a ton of midnight oil on it. Round the clock as much as possible for a few weeks now, it's starting to come together!
