I think it has to do with the search engines finding the sight. Pretty soon people will be able to search for poetry and somewhere in the million and have responses of what it finds will be CRRs poetry. That was part of the reason Macon went to the need to be a member to post.
But I've been wrong before
But you're right this time! And I was in a hurry earlier, it's a Googlebot.
And it didn't take then long to add everything to the index. Copy some obscure and unique part of one of your posts and paste it in the Google search box. I tried "Macon also commented in a pm that he was back" and there it was.
