No need to report updates that are only days old.
The mod manager downloads the latest descriptions weekly.
I have a script that monitors changes to text in every thread linked from the Master Mod List.
Every two or three weeks, I run that script and update the descriptions, eyeballing changed/new threads.
Occasionally, I overlook something. More often, I miss the chance to hash old versions of mods that update frequently. So if a mod's still descriptionless after a month, or you have a previous version of a mod whose current version
is covered, that's when reporting will probably be helpful (title+version+hash+url).
