I think the "help page for pools"https://e621.net/help/pools should be updated to say how the Add To Pool button brings up a popup with a list instead of redirecting to another page and how the Import link is now at the top instead of bottom.
Also, just to confirm... Pools may only be deleted by the creator, correct? I get confused when I see a delete button and think any 'ol person could up and erase a pool from existence.
