From the changes on Github it looks like they get this message:
You will receive an email confirmation soon when you can log your shiny new account - usually less than one business day. Stay tuned!
Several have been in the chat to ask about it, but this may have been updated later. Previously they were getting a nasty error when there was not enough SP to delegate. It's vital to give new users a good experience. Looks like you are on the case.
I'm not sure where is the best place to check the number of active accounts, but it looks like very few were added in the last couple of days. I know some people are actively recruiting, so I hope you are ready for them ;)
Thanks for the update
