"Organizer language" is not a thing in this context, because this notification is sent to a list of emails, not to specific users. I think that would make sense here...

Similar bug: When you create a registration for someone else as an event organizer, that user receives the registration notification email in the organizer's current language.

it wouldn't be too hard to write a plugin for this which notifies admins or deletes files flagged as malicious

I don't think UI for it makes much sense as this should probably be asynchronous anyway. just send an email to the user who uploaded the file.

and no, this method isn't even used for material uploads

We added support for syncing a while ago (but make sure to read the caveats), but for some reason (which I don't remember) explicitly excluded the email from the `locked_fields`...

I agree, mixing two unrelated things in the same issue is messy. Also, "is it possible"-type questions belong in the [forum](https://talk.getindico.io) IMHO

The description already supports markdown, so adding a link to an external page would be easily possible. Not sure about images, technically it'd work, but it might look awful due...

This is because only venues/rooms from the Room Booking system are autofilled right now. There's no such thing as a predefined venue/room on the event level. I guess one possibility...

Yes, we do want to support favorite events and most likely also favorite contributions(/sessions/tracks?) within an event. related: #1662
