Friends Reunited show your password in clear text on an insecure (HTTP) page.
I emailed them to tell them I was concerned, and was reassured (unfortunately I can’t find the email any more) that the page was perfectly safe, as you’d need my password to get there in the first place.
I replied to tell them that the password was being displayed clear text on a page that had not been secured with an SSL certificate, and hence the whole HTML page was probably cached on a number of servers in-between (such as my ISP’s). No further response was forthcoming.
