You can compare your own success with others, by clicking "Players" in the top menu. The information you can see about others are pretty much
the same as you can see about yourself in your inventory.
The chat can be opened by clicking "Parley" at the top menu. It will open in a new windows so you can play and chat side by side. Not a very
feature rich chat yet though...
You can leave messages to each other even if you are not online by writing guestbook entries. The user will get notified by email if he or she
hasn't turned this feature of. If so, the user will still be notified the next time he or she logs in.
