Does it ever give you the creeps that, whenever you get an evite, it knows who you are? Worse, if you forward an evite link to a friend, when they view it, they can change your reply, or even your evite profile!
To view an evite anonymously, remove the &src=… parameter from the URL (if any) and add &unknownUser=true to the end. This link is also safe to send to friends. (That’s not as important any more, though since most evites let you invite other people “officially.”)
