When you check our an item from the group inventory, it should be logged in the system.

Go to My Stuff → My Equipment to view the items that are currently checked out to you, as shown at right.

Some groups allow members to check out their own items.  To do this, click on the Check Out Group Equipment button.

This will take you to a page that lists all of the group equipment that is not currently checked out to anyone.

Click on the box to the left of each item that you've checked out.

Notice that the date you checked out the item is automatically set to the current date;  you can change this to an earlier date if that is more accurate.

Be sure to press the Save button to save your work!  The system will then redisplay this page with your updated information.
