When you get an email from any website that contains a special link that logs you in, never forward that link to someone else, and don't post the link to a forum.
That's what needrain did. He copied and pasted the private link that was emailed to him, right into a thread here at ATP. Hamilton then clicked on that link and then he was logged in as needrain.
The solution for everyone is: if you have a special access link emailed to you, never forward that or give it to anyone else. This applies to ALL websites, not just Garden.org.
