Simple request: I can't seem to find the link to add friends, which is different from inviting friends.  I know it's just a simple link somewhere, so maybe i'm just not paying close attention.  Please help! Thanks so much.

When you visit someones profile, just click the "Befriend" option under their profile picture.  They then will have to respond by going to their account where it should show that tjhey have a new freind awaiting for them.

Hope that helps.
