However there are some nice tools and options to make use of. readme.txt Markdown-based machine-readable file. It’s main purpose is to be parsed and presented by official plugin repository, but it’s not too convenient outside of that. It is great and fitting … Read more
For any rating functionality I always turn to GD Star Rating by Milan Petrovic. This plugin can do SO many things, including thumb rating, rating of comments, multiple ratings, etc. It can also handle Rich Snippets (for getting your star ratings shown in Google SERPs), caching mechanisms, etc..

I recommend not deleting the terms at the point of deactivation. Instead why don’t you delete the terms at the point of uninstallation? You can use the uninstall hook: http://codex.wordpress.org/Function_Reference/register_uninstall_hook Or bypass that. The plugin should create a file named ‘uninstall.php’ in the base plugin folder. This file will be called, if it exists, during … Read more
