We'll create fresh WordPress site with Auto-tags installed. You have 20 minutes to test the plugin after that site we'll be deleted.
This plugin uses the yahoo.com API to find the most relevant keywords from the content of your post, and then adds them as tags.
The tagging is fully automatic, so if you’re using a plugin like feedwordpress to display RSS feeds on your blog as posts, everything will get done as the feed posts are published. No user intervention necessary!
