We have been working to improve the blog section of the site.
You can now manage all your blog posts on one page. Login and then use the drop down menu (top right) and select add a blog post. To the right of the page you will see the titles of all the posts you have added, in date order from newest to oldest. You can also get to this page, to edit a blog post from the buttons on each post in your listing (whilst logged in).
