A general question about the site set up:

I have noticed when I click on any article from the main menu and open the article, it doesn't show where the article belongs to, which section ( Fabrics and materials, Corset patterns , etc, ) like it used before. Now I know that doesn't matter much but it got me a bit confused because that option was helping me to settle on the site and also later was easier to search for the article , maybe some other users would agree

I didn't use that function, but unless it needed to go you could probably email in and request they reinstate it. That sort of change is usually just an oversight.
