Github doesn't mean much to me since they're probably working locally and intend to make large commits. As for waiting, they already have a testnet, so I imagine the public alpha will just be a less buggy version of what they have.
Yes you are right, SHIFT dev team is working on a private repo, they will release the code as soon as they finished because there're many projects outthere trying to implement something on IPFS and they do not want a bad competition that steals all the work done
how many DEV in SHIFT TEAM ?

Looks like six!
https://www.shiftnrg.org/theteam/The verification email does not work.
I also had an inquiry regarding receiving SHIFT from delegates. As I understand it there is only a web interface for this. What if it goes down, ever?
If the verification email didn't work that's probably a Ryver issue, I would try again.
What do you mean receiving Shift from delegates? Like pools?
Currently it's just the online wallet and a linux version for the delegates. However, Phantom previously had a windows version so I would assume that the re-release of Phantom will have a windows version as well, so more people can run their own wallets a bit easier.
