Click on [Queue: Student sign up] on the main class web page and fill in your name and the name of the machine at which you are sitting (look for labels on the processor box next to your display) and click on Launch. A window will pop up.
If a TA is currently accepting requests for help, the first line of that window will say The queue is active. If you click on Add, your name and location will be added to the queue. When it is your turn, the TA will come to your machine and help you.
If you decide you don't need help after all, click on Remove to remove your name from the queue.
If a TA should be on duty but the queue is inactive, please send mail to teach-cs2000@eng.utah.edu
