I Like that build very much. Didn't noticed any bugs or errors what so ever till now. Well, that's good.
The Skip Ahead ring is temporarily closed in anticipation of the build leaving the new development branch.
I have upgraded SOME Skip Ahead systems 19008 -> 19013 from the network. Thus Skip Ahead is not yet closed.
18363.449 was never on skip ahead, you mean people who now sign up from 18363.449 for the skip ahead ring are rejected?
