The Supr plugin for WordPress enables users to easily post links to Twitter and Facebook. It supports the features below.

• Easily post to Twitter and Facebook when you publish your blog directly in WordPress
• Customize your post or one click post with your blog title
• Host short URLs on your own domain
• Search engine friendly short URLs (301 redirect)
• Drive more traffic with the self-hosted StumbleUpon toolbar

Installation

1. Download the plugin archive and expand it (you’ve likely already done this).
2. Put the ‘supr’ folder into your wp-content/plugins/ directory.
3. Go to the Plugins page in your WordPress Administration area and click ‘Activate’ for ‘supr power’.
4. Go to the ‘supr’ options page (Options > supr) to set your preferences.

Supr account and API key

You can sign up for an account at http://su.pr/ (use invite code: “suprbeta”). Your API key and account name can be found at http://su.pr/settings/. Simply enter the API key and account name on your ‘supr’ options page in WordPress and you are ready to start posting to Twitter and Facebook.

Short URLs on your own domain

You can have short URLs on your very own domain (i.e., http://yoursite.com/asdf).  If you are hosting your blog at the root of your website (i.e., http://yoursite.com/) then simply following the simple 3 steps below.  If you are hosting your blog in a sub-directory (i.e., http://yoursite.com/blog/) then please following the instructions at Supr:Short URLs on your own domain.

Step 1: WordPress Settings

Go to your ‘supr’ options page (Options > supr) in WordPress and select the option to host short URLs on your own domain and click ‘Save options’.

Go to your ‘Permalinks’ options page (Options > Permalinks) and select a permalink option other than the default (i.e. Day and name) and click ‘Save Changes’.  Note: even if you have already selected an option other than default before, you will need to click ‘Save Changes’ again for the hosted short URLs to take effect.

Step 2: Sync your settings to Su.pr

Go to http://su.pr/settings/ and enter your domain in the Promoted Websites section.  Click “Save settings” and our servers will fetch your settings from WordPress. Verify that your setting is synced with Su.pr.

Step 3: You are ready to go!

Try shortening a link to one of your blog post and you should have short URLs on your very own domain!
