If you cannot access the Volunteer View (or User View), you’ll need to add yourself to that module by editing your administrative profile:
Go to the My Profile Menu (the green profile icon, or your profile picture, at the top right), then click “Edit My Profile”
Click on the “Miscellaneous” section in the “Main” tab of your profile
Select the “Volunteer” tab
Select any Status (except for “Archived”)
Click the [Add to Module] button
Note: Once the Module is added, it will take about 15 minutes for the change to take effect, and you may need to log out and log back in to use this feature.
