Toivo,
No problem. You should bring this up as a feature request to your SE. They can file a feature request for you.
At this point you'd have to create documentation to educate your users. I've seen some people put informational screen shots onto the login page to help inexperienced users out.
Toivo,
We're in the same situation as you're in - trying to notify the user that their NC session is established - have you received any solution workaround to implement this?
Thanks
Srini
No, sorry, no solution. Let us know if you come up with one, though!
