I've come across a nice WordPress plugin that displays country flag, operating system and web browser used in each of posted comments blog comments.
Its really nice plugin, since it adds some transperancy and colorfulness to each of blog comments
here is a screenshot of my blog with Comments Info Detector "in action":
Comments Info Detector as of time of writting is at stable ver 1.0.5.
The plugin installation and configuration is very easy as with most other WP plugins. To install the plugin;
1. Download and unzip Comments Info Detector
linux:/var/www/blog:# cd wp-content/plugins
linux:/var/www/blog/wp-content/plugins:# wget http://downloads.wordpress.org/plugin/comment-info-detector.zip
linux:/var/www/blog/wp-content/plugins:# unzip comment-info-detector.zip
Just for the sake of preservation of history, I've made a mirror of comments-info-detector 1.0.5 wp plugin for download here
2. Activate Comment-Info-Detector
To enable the plugin Navigate to;
Plugins -> Inactive -> Comment Info Detector (Activate)
After having enabled the plugin as a last 3rd step it has to be configured.
3. Configure comment-info-detector wp plugin
By default the plugin is disabled. To change it to enabled (configure it) by navigating to:
Settings -> Comments Info Detector
Next a a page will appear with variout fields and web forms, where stuff can be changed. Here almost all of it should be left as it is the only change should be in the drop down menus near the end of the page:
Display Country Flags Automatically (Change No to Yes)
Display Web Browsers and OS Automatically (Change No to Yes
After the two menus are set to "Yes" and pressing on Save Changes the plugin is enabled it will immediately start showing information inside each comment the GeoIP country location flag of the person who commented as well as OS type and Web Browser
