So, I was looking at the recent speed runs when there was a section titled "Notes" what does this mean and how does it change?

Can you please send a screenshot or a link to the page?

There's no specific page to find the little "Notes" section, but this was the first page I saw it on (you may need to scroll down). https://www.speedrun.com/roblox_doors/run/ylnnejxz

When submitting a run, the user or moderator can add a description about that run.

Ah okay, thanks for the help, Bacon.
