If you are new to Ning networks, it takes a bit of time to find your way around. One thing I didn't notice is the bar a the top of the page. Find your email (and new mail notices) and friends list (and friend requests) there. If you belong to more than one ning network, your friends from all networks are listed.
Check it out.
Look at the top left of your "My Page" (you may have to scroll up)
- Click your Icon or Name to see your Ning Friends and the Ning Networks you belong to.
- Click the envelope icon to go to your Ning message center (If theres any new mail it'll say "New" beside the icon.
- Click the little man icon to review the status of friend request - those you sent and any you have received.
