Socializer! is a fast plugin to share posts on Facebook, Twitter, Reddit and more top social networks, Google Plus, by eMail, even translate them...
To install Socializer! follow the usual way of installing WordPress plugins: unzip the archive and upload the "socializer" folder inside the plugins folder of your blog, then activate Socializer! and configure it. Both content and widget options are configured from the Socializer! admin page at the Settings section of your blog.
For WordPress multisite MS / MU installations you can activate the Socializer! globally, for all the sites of your network, or just install it on the main (network admin) site, leave it deactivated there, and activate it on (any number of) individual sites in your network.
You can also create occasional share-links manually, if you need to, when you write a page or post and make references to some other post or page. Read instructions for this at Socializer! Downloads
