I just added the facility to my weblog software to edit previous posts, due to a rather nasty ambiguity in the last post (which is now edited!).
This post is to test that I didn’t break the page to add a new post, whilst adding in the edit page.
Writing this post is also shown in the current screenshot, so you can see what I use to edit my weblog. Why you would want to know, I’m unsure, but a couple of people have asked in the past.
