WordPress Discussion Settings
WordPress Discussion Settings provide a ton of options for the management of comments and controlling links to your posts/pages.
The first section is for default article settings. The first setting deals with links you make to other blogs. The second deals with pingbacks and trackbacks, or links back to your blog. The third setting is the default article settings that allow people to post comments on new articles. If you’d rather not allow people to comment on your posts, uncheck this box.
In Other comment settings, you can choose the guidelines for how people post comments and how their comments are handled.
Next, in the email me whenever section, you can choose to be emailed when someone posts a comment or when a comment is held in moderation.
The Before a comment appears section deals with how comments are published. Here you can choose if an administrator must always approve comments or to publish automatically if the comment author had previously posted a comment.
In the Comment Moderation area, you can customize how a comment is held based on the number of links. In this box, you can also add words, names, URLS, emails or even IPs to filter comments into the moderation queue. Both this section and the comment blacklist section are great for helping to defend your blog against spam comments.
Next, take a look at the avatar section. An avatar is a profile image you can have assigned to your email address when you comment on avatar-enabled sites.
Here you can enable the display of avatars for people who comment on your site, filter by their rating or chose a default avatar for people that don’t already have a custom one of their own. If you don’t already have an avatar, visit gravatar.com to upload your own.

WordPress Media Settings
The Media Settings page allows you to set maximum sizes for images inserted into the content of a post. These settings are great for saving time if you always want images to be the same size or if you want to apply default settings for medium and large image sizes.
The Uploading files option allows you to select whether or not your uploads are organized into month and year based folder.
Click Save changes.
WordPress Permalink Settings
Permalinks are the permanent URLs to individual pages and blog posts, as well as category and tag archives. Basically, a permalink is the web address used to link to your content that is permanent, and never changes— that’s why they’re called “perma”-links.
The WordPress Permalink Settings screen allows you to choose your default permalink structure. You can choose from common settings or create custom URL structures.
By default, WordPress uses web URLs, which have question marks and lots of numbers in them. You’ll probably want to change your permalinks here to another structure to improve the aesthetics, usability, and forward-compatibility of your links, and to make them more search engine-friendly.
If you’d like more information on setting up your permalinks, click the Help tab at the top of the screen. Here’ you’ll get an overview of common settings and structures to help select your permalink structure.
