This plugin allow your visitors to attach images or other file to their comments as easily as possible.
19. Quote Comments
This plugin adds a tiny link that says “Quote” on each comment on your posts. Click it, and the contents of the comment is copied to the comment area, wrapped in blockquote tags. It’s even compatible with MCEComments plugin.
For each user comment plugin will create a new dynamic page on the blog, holding the actual comment information. This page will not actually exist in WordPress database, but we will create it dynamically using a WordPress plugin.
What we instantly get in this way is big jump in site’s index visible to search engines. This is possible because blog comments are crawl-able, index-able and most importantly rank-able content. Also meaning you will start to get search engine traffic for the context of the comment.
The TTFTitles plugin is another dynamic text replacement plugin that lets you replace your headers with images using any TrueType font you choose. It’s mostly a rework of the Image Headlines plugin. It has been tested with WP 1.5.2 up through 2.7.
Smileys in comments is also supported, and may be inserted using the standard emotion shorthand or through the CTI interface introduced in TSE 2.0.1b.
This plugin numbers your comments sequentially and hierarchically, with full support for the new comment features available in WordPress 2.7 and later — including threading, paging, and your choice of ascending or descending date order.
An extremely powerful WordPress anti-spam plugin that eliminates blog comment spam, including trackback and pingback spam. Finally, you can enjoy a spam-free WordPress blog! Includes spam-free contact form feature as well.
The Simple Pull Quote plugin lets you insert pull quotes into your blog posts to emphasize certain sentences or phrases using custom fields. Pull quotes can be styled by editing the included CSS file. It works with WP 2.7 or 2.8.
27. AJAXed WordPress
AWP’s basic features include inline paginated posts, inline comments, threaded comments, the ability to submit comments with AJAX, pagination of your homepage, live comment preview and much more, but it does not, however, force you to use any feature, and it also allows all aspects of the plugin to be easily customized through a single Administration panel. It also has special features that will ensure compatibility with many other plugins.
There are many comment-related plugins in WordPress plugin directory. However, if you’d like to find just a simple comment-posting Ajax plugin, you won’t find any. That’s why I developed a simple and small (5kB) yet functional Ajax Comment Posting (ACP) plugin. Not only will it post your comment without refreshing the page, but it will also make sure that you’ve filled all the form fields correctly.
