Need help to adapt Telescope app

I have a Meteor web app where I want to include a forum feature. upon clicking ‘Forum’, user will be redirected to a new subdomain which will open the Telescope app. My specific requirements are:
1)The community discussions should be private and only logged in users should be able to see the discussions
2)Disallow new user registrations in Telescope
3)Authenticate within Telescope, using users present in Meteor.users collection of my web app
4)If possible allow automatic login to telescope once a logged in user inside my web app clicks on Forum

I know this can be done, but my technical skills are a handicap. I learnt coding 2 months back and this is my first attempt at building something :). I am using Meteor 1.2
