CommentGator is a freeware tool which lets you comment on any wordpress blog without visiting the blog in your internet browser, In the program interface you can either comment on a specific topic which you like to read and comment without visiting the blogs. It is a simple to use blog commenting tool.
How To Use This Blog Commenting Tool
1. Type the topic for which you would like to read the articles and click Go button on the application
2. Now type in your name, url and email as shown below, and press the Inject Comment button to leave a comment on the blog post.
I have not tested this tool on those blogs where where some comment fighting spam plugins are implemented. Although this isn’t an automated spam tool, this is a tool for people who want to read, comment and move on to the next blog quickly without having retype everything in. Comment are not automatically submitted and you may still need to type in authorization and anti-spam codes to submit on some sites.
