Archival solution

[yarikoptic]

For notes, polls, chats, and possibly even videos.
Should also support personal/private archival.

I love git, git annex! I think we can make archival happen into git repositories on GitHub or dedicated gitlab or gogs installation quite easily! Could use git annex for videos, eg "add to my archive" button for a poster or video would add a file with URL to personal archive git/git annex repo there! As a result, upon completion of the conference there would be central archive repo and outside user specific repos. The only shortcoming is that decision to make private/public for user specific archive would apply to the entire repo. Workaround could be via git annex, but IMHO it would make setup too complex to support that.
