Forum .LRN Q&A: Re: granting privileges to community relational segments

You can grant specific privileges to particular group of people using permission UI that can be reached through the site-map (permissions link), in your site-map, find the dotlrn/ folder, and then dig until you find your club or class, and then, inside it you'll find the instances of different packages for that given class/club (including calendar instance), then you can set permissions for that given package instance to a group or user's.
