It's good that this site was finally made, however I think we should have a second contingency as well (TD should have one too but they havent really jumped on this yet...)
I propose a Telegram and/or Matrix server in addition to .win, as neither of those are subject to Cloudflare BS, DDOS, or domain registrar hijacks. Those of you who have been paying attention are well aware that something big is about to happen, and killing communication is a required part of their plan. If we only have one basket to put our eggs in, they wont have much trouble breaking them.
They all have the same weaknesses though. Aside from the three mirrored website backups, it has discord (killed), telegram (unofficial and dead, like 10 users), and matrix (same as telegram)
Websites have fatal flaws as I mentioned above, but having Telegram/Matrix backups is effectively foolproof and should be pursued.
