An interesting post from Blogger Tips and Tricks dropped into my Google feed reader on how to check links in your posts. Click on W3C Link Checker to see if your blog links are all in order. I found two broken links in my Arts and Stuff blog sidebar due to domain changes. If you have been clicking on the following two links without success with them loading up the website, they are now working.
For your interest I didn't tick any of the boxes on the W3C Link Checker page before starting the search. Also I searched my whole blog rather than individual posts.
The Art Gallery of South Australia
