Comment Autogrow


Getting comments on your site is one of the most important goals. Longer comments tend to be especially valuable.

However, most comment textareas have a small height, making it difficult to write long comments.

Enter Autogrow

Here’s how it works: When a commenter almost fills the textarea, instead of getting a scrollbar, the textarea grows in height. This means they can see the entire comment while it’s being written, no matter how long it is.

It uses the Growfield plugin for jQuery.
