From your short remark it sounded more like you were suggesting I submit changes to gerrit to get development moving more quickly. There really isn't much going on on gerrit either from what I've seen. I guess that's the "outside" part your talking about? So can you tell me what is the point of having this thread and open source if most of the initial development is private source?
As far as gerrit registration, you can't sign in if your email won't register.
I specifically said registration and not sign in.
