This new version of Premium Contents WordPress Plugin has some improvements on administration side and a new “user action” to unlock contents, the “press that like button”. This new feature blocks contents until the user press a Facebook like button which add a +1 to a defined URL (for example the URL of your blog or of your fan page).
I think it’s not legal, by the way.
Second important new feature if the PayPal refunds management, so if you refund someone from PayPal his account should be updated on the blog too (setting the expire date to the origins – 1/1/1970).
The WordPress repository has now some screenshots (even if I added them without checking if they show up…). Hope this new version is easy to configure!
