I tried adding this on the site, but it just sits in the text box at the top and doesn't create an idea or do anything. Not sure what's up with that.
"Add a method to expire programatically or detect auto-created posts"
It would be nice if the plugin detected any new post created, rather than only those built by pressing "New post". I use the plugin "Automatic Featured Image Posts" by Jeremy Felt (http://wordpress.org/plugins/automatic-featured-image-posts/) to auto-create posts when I uploade image batches, but they don't get the default expiry date.
The alternative would be to batch add a date in the post list or similar - I could just up the images as Drafts, select all, set date - but it'd be nice to have the plugin do it automatically.
