Whilst he might not post a picture or update since february he was last signed in yesterday (see his profile), it might be worthwhile sending him a quick PM and let him know what you think of his work.
It's good when someone recognizes the effort you've gone to, I'm not saying MM hasn't posted because he got bored, maybe life just prevented him from doing some more pictures/stories.
I'm sure MM will do more stories at some point, he seems pretty creative
