Again, with my new project. Here is how to YY7 service to short your post links, and send it to Twitter:

• Go to your Wordpress Dashboard
• Plugins
• Add New
• Type “YOURLS” and click “Search Plugins”
• Choose “YOURLS: WordPress to Twitter”
• After installation, go to settings to “YOURLS”
• “You are using” and choose “your own YOURLS install”
• Then, choose “Remote, on another webserver”
• Put this link: http://yy7.com/api.php
• Don’t write anything for  password and username
• Put your Twitter login information
• Then, choose the settings you want and click on “Save Changes”

And now, enjoy using a dot com and keep the environment clean from domains like .ly,.ch or .la
