This is a good question.
Half the reason this hasn't happened is because I haven't prioritized doing this, despite it being a good idea. It's one more thing that I would need to maintain and update.
Ultimately I'll like to create a website that allows uploading, downloading, commenting, and voting of system files. (and then integrate this into the browser inside of Universe Sandbox).
Does anyone have any experience with creating a database driven website like that and would like to help?
