This is the main page here. From here, you can view everything about the simm short of the personnel (viewable by clicking the link in the nav bar at the top of your screen).
The missions, in which are contained all of the in character posts, are first. The missions will include everything within the current mission group; the mission groups will show you all of the mission groups currently assigned. You can also view crew personal logs, which are a great way to learn about the crew's inner most thoughts.
Stats will give you an overview of what the simm activity has been of late. The crew awards will display every award that can be won and who has achieved each of them.
Tour will take you to some of the locations on the station, specifications lists all of the main information, deck listing tells you where everything is located, and departments gives you a quick rundown of each department and what they do.
