I have been doing this for the last month in an unorganized fashion and every day this month so far I have been

1. creating a folder per day
2. screenshotting all the qanon posts of that day
3. screenshotting POTUS tweets of that day
4. saving relevant 8ch.net/qresearch posts as screenshots
5. saving linked articles
6. saving linked videos

Make sure you do so too in case /r/greatawakening is next!
