Setting up a featured image for a post or page is quick and easy; to do so, locate the featured image box* on your editor page, and select Set Featured Image. When you’ve done so, it will bring up a page from where you will be able to drag-and-drop files, or select them straight off of your hard drive, to select the wanted image.
You can also choose from images that are in your media library, if you already have it added there. 

After you have selected the image, you will have options available to either edit the image or delete it if needed. Once you have finished selecting the right image and editing it to perfection, you can preview your changes or go ahead and publish the page/post with the image viewable to the public.

*If you are having difficulties locating this, it should be on the right hand side of the page. You may need to scroll down a bit to find it.

If you’ve been using WordPress for some time now, you may have come to notice that, by default, it places the entirety of your posts on the front page. This can, obviously, be an annoyance for visitors on your page, as they would have to scroll through blocks and walls of text just to look through it. To absolve this issue, you can create a Post Excerpt.

In order for post excerpts to work properly on your site, you must first go to Settings and select Reading. By default, ‘Article in a feed’ will be set to Full text – set it to Summary and save. Then, go to the Add New Post page to confirm if you have the excerpt module  enabled or not. If you don’t, just go to Screen Options at the top of the page, and check the box for Excerpt. You should now see the excerpt module below the main body for text.
Within the module, you can write a brief summary about your post, copy/paste a line from the post itself, etc., just put in the info you need and click Update.

If you notice that your full post is still being displayed, don’t fret – this is due to the fact that excerpts are meant to work with your posts in RSS feeds, which are generally used with widgets. Within your post editor, you will have an option (above the main body for text) called the Insert More Tag. Place your cursor at the point you would like your summary to end, and select the tag icon. This will separate that part of the post with a line, displaying which information visitors will be able to preview. Once you have finished, just hit update.

Depending on your current settings for comments, you may need to approve them before they are visible on your site. You will see a notification with the number of pending comments on both your side and admin bar. Click on either of them to take you to the comments page, where you will be able to see all of your comments, whether they are pending or approved.
You can filter between pending and approved on the options directly above the comments themselves.

From here, you have a few options for what you would like to do for each comment…
–Approve a comment by simply hovering over it and select approve. If you have approved a comment and would like to unapprove it, you would just do the same actions you did to approve it.
–Reply to a comment, by hitting reply under the comment
-Designate a comment as Spam*
-Send a comment to Trash*^
–Edit a comment, which will allow you to change any aspect of the comment (such as the author’s information, the comment itself, or the current status of the comment)

*Selecting these options will move the comment to the designated filter
^A comment in the Trash filter can still be retrieved, however you will have the option there to permanently delete the comment.

If you ever need to change your password, navigate over to the column on the far left and going to Users, and then selecting Your Profile from the drop-down menu that appears.
At the bottom of the page you will see a text box to enter in your new password, and then a second box below it to confirm it.
Beneath these boxes will be a bar to indicate the strength of your password. 

When you have finished, select Update Profile and your old password will be replaced.
