Eskie, you apparently changed your email address in your profile at some point, but never clicked on the confirmation link in the email we sent you. So you're in a group of users that have some limited functionality. I suspect that is the reason you're no longer seeing that link.

If you no longer have that link or email or can't find it, PM me with the old and new email addresses, and I'll manually update your profile record.

Once you confirm your email, the link should re-appear. (It also won't appear on people's profiles that you're already friends with.)
