Discovered usability issues

Issues	Users	Possible improvement
Could not post a tweet because was not registered on twitter and did not wish to.	User 1	Create independent data base for tweets.
When navigating Google Earth, tried to use mouse and did not figure out immediately to use keyboard controls.	User 1	Support mouse navigation alongside keyboard controls.
Was confused when taken to teleport's navigation window because did not know if the other person is still in chat mode.	User 1	Make it more obvious that person's live chat window moves to the sidebar, when system's mode changes.
