I've noticed that many new threads with small edit requests are opened and users having to refer them to the main Edit Requests Thread.

That's why I think the Edit Requests Thread should be pinned on the Forums to make it easier to find.
Maybe you can put it on the left side below/above "Bugs, Suggestions, Data, Chat, API, Pending Features" with a big icon and a small description.
