If you're in your district email and need to submit a Help Desk ticket, you can initiate the process from there.
1. From your district email account, click the Google Apps Switcher in the upper-right corner, then scroll down or click the "More" button
2. At the bottom click the Zendesk icon--the Help Desk should load automatically
Once you're at the Help Desk you're ready to submit a ticket. See the write up on that here.
