I just put live support for SSL on the admin section of the Recycling Group Finder. You will notice this if you ever need to log into the site as an administrator as you will be redirected to a URL starting with https, as in this screen-grab:
What does this mean for me?
SSL stands for Secure Sockets Layer, and basically means that any data transferred over the connection is encrypted and therefore secure. You can read more about it on the wikipedia page. As a group moderator you don't need to know the details though, just that now whenever you log into the site to make changes your username/password and website session data are un-interceptible.
Let me know if you see any problems with this at all!
