The Plus One 2 Unlock plugin allows to lock a part of content on a page until the user clicks on the Google Plus One Button. What’s more, you can show the locker only for Google Plus users, and hide it for others.
If you’ve always fantasized that WordPress would fix their search results and return something actually relevant (not ordered by date), but are let down on every new release. You’ve found the plugin to make that dream come true.
Relevant Search actually replaces the default WordPress search with relevant results. After testing a ton of plugins on the Tuts+ network without any luck I finally had to write one that worked. Go check for yourself, search any of the Tuts+ blogs and see this very same plugin in all it’s searching glory.
