Request membership message missing group name

We are using telligent community 10 and we have found that for unauthenticated users (we are using cookies based on our current IDP) when they reach a community page they receive the following message. 

I have 2 questions:

1. How do we change this message in telligent to be more friendly?

2. Is it possible to simply redirect the user back to login page?

Thanks

Luke
