Looks like the post that you were notified for showed up about 7 minutes or so after you posted this here.

Did you only get this one notice? It is possible that if a user is posting a picture you will get a notice when they hit the submit button although the post is not yet up in the database yet.

Is strange and I'm aware of several weird email problems we have now and think its the email sending program...I am exploring alternative mail packages to see if this will fix the problems as this is the last big bug I need to squash as the image upload one is now working ok.
