I forgot to pass along the how to to get to the new post editor.
Here's how: (It's super easy, trust me. It has to be, for me to be able to do it. lolol)
Go to your Dashboard. Click on the "Settings" tab.
Then, if you need to, click the "Basic" tab. (I didn't need to, I was already there.)
Now, scroll down the page until you encounter "Post Editor". Make sure the new version is selected. If I remember correctly, that is the top option. (But don't quote me on it... lol)
Save your changes and you have more options for posting at your little fingertips. :D
There is a link to follow when you change your post editor that will tell you about the different features and tutor you in their use. I read a little, then decided to just dive in and start mucking about. Just diving in and mucking about is how I learn and have learned my few computerly skillz. :D I just decide to try something, jump in and start clicking on stuff. My computer will tell me if it is wrong. Then I back out and try something else or try again. I haven't blown my 'puter up, yet.
Give me time, tho. *evil grin*
