Here's what I used:

r/WorkersStrikeBack

Can we get an official chatroom going?

On matrix/element, discord, telegram or other platforms? Myself and some others prefer chatrooms over forums. Not the ones partnered with r/antiwork. I know of non partnered matrix and telegram chatroom that would work, but you might want to take this opportunity to establish your own.

We are working on a discord atm

I would like to help by bridging a given channel to matrix/element. Matrix is decentralized foss and my preferred platform, in part due to the it being reported that discord generates 130 mill revenue / yr, whereas most matrix servers (actual servers, rather than centralized servers which is what discord uses) are non profit.
