Ever write a blog post that you want to appear on a later date? If you are using Blogger, this is very easy to do. When you are ready to post the blog for a later date, click on "Post Options" at the bottom of the blog post window. On the right hand side, set the post date and time. Then save and your post will appear on the date and time that you had set it for! How convenient!
This same feature is available in Edublogs. Read this blog post for directions on completing this same task there!
So, the next time you have a lot of great blog ideas OR prior to going on vacation, create a few posts and set the dates for them to appear on your blog. Now, enjoy your vacation!
