Setting up SignalK Server in BBN

[mgrouch]

It’s really SignalK question. Not OP question. 
BBN OS just has SignalK installed as is. So there is no admin user
or password set. You do it by logging in for the first time.

‘Sign up’ link has nothing to do with SignalK user or password
It’s a link to sign up to SignalK web site on internet.

I’m not sure you want to call your SignalK admin user ‘changeme’
as the previous poster suggested.
