Comments are a way for visitors to add feedback to your blog posts. If you choose to enable comments for your posts, then a comment form will appear at the bottom of the posts and people can respond to what you have written. Approved comments are displayed on the individual posts, not on the blog home page, so you need to click on a post title to see comments. You can show the latest comments on the home page by adding the recent comments widget to the sidebar if you wish.
You are in control of the comments left on your blog. Users on the blog who have Editor or Administrator rights will have the ability to manage comments. You may also turn off comments if you don’t want to use them.
The default comment setting on your blog will be to allow all comments to immediately be visible when posted. They will not be held for moderation, but the author of the post will receive a notification email with links embedded to view or delete the comment.
You can enable or disable comments site-wide in your site’s Settings → Discussion page (Administrators Only).
The Discussion Settings are used to control how visitors and other blogs interact with your site.
Default Article Settings
In the Default article settings, there are three options. These settings are defaults for new posts or pages, which can always be changed individually on each article. This first two options deal with pingbacks and trackbacks. The first determines if your blog will send out pings and trackbacks to other blogs when you publish articles. The second determines if your blog will accept pings and trackbacks from other blogs. The third option allows you to enable or disable comments by default.
To manage comments, go to the Comments link in the left menu of your blog dashboard.
Sorting Your Comments
There are several ways to view comments. There are filter links for all, pending, approved, spam, or trash comments. There is a search option on the right, and there are links to comment pages below the search box. There are also bulk action and filtering options as well as a button to let you re-check your comments for spam.
When you hover the mouse over a comment in the Edit Comments page, you will see comment actions appear below the comment. You can approve/unapprove, reply, edit, spam, or trash comments with those links.
