How to see Who You've Invited to be a Friend

Go to the "My Page" Tab and scroll down until you see "My Friends" Click on "View All"

This will open up the "My Friends" page. You have two tabs "My Friends" and "Requests Sent".
"My Friends" will list all your current friends. Click on the "Requests Sent" tab to see who has
not yet accepted your invitation yet. If you do not see the "Requests Sent" tab you have no pending requests.
