It is released as 1.0.0, the first version; need to be used on a wordpress where permalinks aren’t activated and this until next more advanced version. In the mean time it is powerful as easy, can be added to the header template page with a simple two lines addition. The plugin has been released and is available for the download. After download the w3 meta keywords plugin file, just follow easy instructions for the header.php template file modification, two lines of code as just explained in the step by step instructions: how to use w3 metakeywords plugin for wordpress. That’s the very first version and any addition, question or improvement is very appreciated.
