How to keep a permanent record of your Facebook friend requests

Once you accept a friend request, the notification "....wants to be
your friend" disappears forever from your Facebook page. How do you
keep a permanent record of your friend requests for future reference?

1. Enable email notifications by following these steps:
(a)Go to SETTINGS & PRIVACY/NOTIFICATIONS. (b) Select "All
notifications, except the ones you unsubscribe from" and click "Save".
*Henceforth, all Facebook notifications (including friend requests)
will be sent into your primary email address (as emails from Facebook
to you).

2. Sign in to your primary email address and do these:
(a) Create a folder/label named FACEBOOK FRIEND REQUESTS.
(b) Create a filter for FACEBOOK FRIEND REQUESTS so that all existing
and incoming emails with the words "...wants to be friends with you on
Facebook" will be automatically sorted into FACEBOOK FRIEND REQUESTS
folder/label.

* Long after a friend-request notification has disappeared from your
Facebook page, you can still retrieve it from your email box's Friend
Requests folder/label and know which friends added you and which
friends you added.
