With the release of WordPress 2.3, users now have access to a built-in tagging system that previously required the use of a WordPress plugin, such as Ultimate Tagging Warrior (UTW) or Simple Tagging.
Unfortunately, both of these plugins offered some functionality that is not yet available in the default tagging system. If you are missing features such as getting recommended tags, auto addition or subtraction of a pluralized tag (examples include mentioning Vista but your tag is Windows Vista or your post mentioning download, but your tag is downloads), and a type-ahead auto completion feature, then Ryan of CyberNet has a solution for you!
This WordPress plugin is called Recommended Tags, and it was built only for the tagging system in WordPress 2.3 or above. Simply upload and activate the plugin, then begin using it to assist you with your tagging!

Nicen themes, good work :) 
Being a heavy tag user, I think the features in this plugin justifies adding it to my growing list as well to all my WP blogs.
Thanks for the heads up, Kyle!
K – You are welcome. This plugin saves me a lot of time on my various websites.
Kyle this is a great plugin, thanks for telling us about it. Just what I needed!
No problem David. Glad you found it useful!
this is a great plug-in! one of the things i noticed right away after installing it was that i’d accidentally created a couple of nonsense tags. i’m sure i would have noticed eventually, but having the tags right there on the post page made it blatantly obvious.
