Plugin: Wordometer Documentation
To install this plugin follow the instructions found in the Easy Plugin Installation Guide
Visit Preferences > Plugin Settings > Wordometer to set the highlight indicators on the Body and Extended fields. The highlight indicators can be used to set word count goals; just enter the minimum and maximum number of words to trigger the highlight indicator.
It’s really easy to use Wordometer because… well, there’s no work involved for you — Wordometer handles it all!
Visit the Edit Entry page. If you create a new entry, Wordometer will count the number of words or tags as you type them. If you edit an existing entry the words and tags in each field will be counted when the page is loaded, and will be incremented as you type.
