Changing Number of posts on main page

The logic is the last post will come on the main page. We can decide the number of posts to appear on the main page. The default value is 7. But if 7 posts appear on the main page, it takes some time for the page to load. To over come this, we can change this.

Go to Dashboard. Click Layout. In that, click 'Edit' under BLOG POSTS. IN that, first option is 'Number of posts on the main page'. Give the value you want. If you want one post, then give one. Save your settings.
