Gadgets

Q: what is a gadget, how do I add it to my blog, and how do I get rid of it?
A: A gadget is anything you add to your blog other than a post. Gadgets used to be called widgets and page elements. On your blog now the gadgets are: Followers and About me.
Unlike other blogging platforms (word press, my space, typepad, livejournal, multiply, facebook, orkut, friendster, hi5), on Blogger, we do not call a blog, a blog. We call it a post. When you wish to make a new blog, you should click on "new post". Other wise you would be creating blog after blog and not a single post.

Adding a post
1. Sign on to your blog using your ID and password here: www.blogger.com
2. On your dashboard click on "new post"
3. Type inside the post editor (large box) or upload a photo
4. Publish post.

Your blogging area will be filled by your posts as you add more posts. The side bars are meant for adding gadgets: About me, archives, labels list, link list etc.
Continue to add posts to your blog. One blog is usually enough for new bloggers. Please do not create any more blogs today!
