Wordpress to Twtter in 126.96.36.199
This plug seems to support custom post types and I have intsalled and set it up, ready for testing.
ou.gd - WordPress to Twitter
ou.gd is a free URL shortener service you can use to shorten any link and share it.
This plugin is a bridge between ou.gd, Twitter and your blog will tap into the ou.gd API to generate a short URL for it, and will then tweet it.
