Writing and editing a post in Blogger

1. Click New Post, and don't forget to add a Title (above the page)
2. Use the icons to manage the text.
3. Save it to keep it in draft form, and when finished Publish to put it on the web immediately (and no doubt return to update it later).
4. See the Post settings to the right, and add Labels to help readers find topics, modify the date to alter the order of Posts (click Published on) 
5. In writing, use the web to add value to your message.
1. Add images wherever helpful - grab images from the web. Learn screen capture, to grab parts of images. [Windows 8 Snipping tool, Apple Cmd/shift/4]
2. Add links: "One of the main predators of roses is the aphid, which will quietly suck the juices out of your most precious roses." See the Link button on the editing toolbar.
