The most recent version of the WP Dictionary Plugin introduced automatic linking within your Posts.
Now, all it takes is the click of a button to add links to your dictionary words throughout your entire blog.
If you'd like to dynamically include dictionary entries or a dictionary menu, you've got the tools available to you with easy-to-use shortcodes.
Just access the inline-documentation for a reference to all your options.
You don't have to wait. It's ready now.
Don't wait too long. The plugin is always being improved, features are always coming down the pipe, and the price is getting raised with every improvement. Get it now, while it's still cheap.
