If you have started a working session and wish to stop it, you must close the Markstrat application by clicking the Logout button in the left bar.
Do not close your browser without logging out, especially while you are making decisions. If you do this, the decision form that you were using when you closed your browser will be locked for about 20 minutes, until you are timed out by the Markstrat application. Your teammates will not be able to access this decision form during this time.
