Yep, been self-hosting it locally for a while now. To put simply, I archive anything that is within my personal realm of interest that I believe has a chance to be deleted, and is important to keep a copy of. It could be troubleshooting tips for specific tech issues, things that may be under threat of takedown, or maybe just an article I like and want a local copy of. It’s a wonderful tool.

Sorry for the late response, but yes, I believe you can. There is an option in the config called allow_public_upload which can be changed to true or false.
