Raad,
- give me more data about calendar dependencies? What's happening incorrectly?
- subgroups: there are default behaviors we set up for Sloan which may not be immediately intuitive. You can't join a subgroup if you're not a member of the parent group. Or are you seeing a direct bug / error page?
- not seeing forums: did you make your users "guests"? Can you see the forums administration interface in the control panel?
