How do you know when you get a friend request?
A notification will be sent to your e-mail. If you aren't receiving e-mails then chances are that you have your notifications turned off. To turn them on, heres what you need to do: - Go to your profile - Click "Edit My Profile" - Click "Toggle Site Notifications" - Then hit the big button to confirm.
If that doesn't work then your e-mail probley has FunAdvice e-mails marked as junk or you have provided a false e-mail address.
...in which case, add "funadvice.com" to your safe senders list. (if it's going to the junk folder).
