I am running Wordpress 3.1.2 with multisite enabled. I am trying to find a reliable plugin that can auto post blog posts to Twitter and Facebook. I am using WordSocial. (http://wordpress.org/extend/plugins/wordsocial/) - I can configure it fine when running Wordpress (not MU), but I can't get it to work with my MU install.

I am not getting any errors, it just won't post to Twitter or Facebook. I've tried just about everything I can think of.

Autoposting to the social sites is a popular functionality - can anyone try out this plugin and see if they can get it to work? Many many thanks.
