I would like to announce a new plugin which I have written (my first), called WP to GHTime. This plugin allows you to protect the content of your blog by generating a GHTime Code which timestamps your blog entry so no one can steal your posts and claim them as their own.
From the readme file:
This plugin is essential for anyone wishing to protect their intellectual property.
The Wp to GHTime plugin allows you to protect your intellectual property by using a GHTime Data Protector Code to timestamp each post for you. The GHTime code is displayed at the bottom of each post and can be verified by clicking on the code.
Each code is unique and provides proof that the information contained in each of your blog posts belongs to you.
You can grab the plugin here: http://wordpress.org/extend/plugins/ghtime-plugin/
Let me know what you think :)
