I need a plugin for wordpress that allows posting on twitter and facebook. I now that already exists some plugins with the similar functionality but I need my own plugin due to some copyright issues.
The plugin should include these features:
-Post to twitter the link of the last WP blog entry using URL shortener service and allowing user to include hashtags or customized text
-Post to facebook profile allowing user to include wanted text or comments.
The plugin use should be oriented to usability, so the way to activate the plugin it has to be "simple login" in both services.
