Private Post
hm I forgot to post picture on here
You can now create private posts on Posterous to share with just a select group of people. Simply email private@posterous.com. We'll reply back with a secret url that you can give to the people who you want to share that post with. You can also make a post private on the post editing screen.
This post won't show up on your public Posterous site, or in your RSS feed. And if you have Autopost set up, private posts will NOT be autoposted to your other sites.
As always, send feedback and questions to help@posterous.com.
