I will try to quote my that post as much as I can until everyone become aware of this method and help people who have problems about this function accordingly. I see no point at deleting all other e-mails while this obviously better method can be done with a couple of mouse clicks.

Even if you fill all e-mail blanks in an Edit Contact window, (Personal e-mail, Work e-mail, Other e-mail, Other instant message address), just select "Instant message address" from the drop-down list for the "Primary e-mail address" option in "Contact" tab of "Edit Contact" window. Now you can use "Messenger Plus! Features..." menu items without the need of deleting all other emails of contacts from Edit Contact window.
