For a while, the Golem community moderators have begin looking at alternatives to the current Golem Rocket Chat (previously hosted at https://chat.golem.network). The reasoning behind this is a combination of factors; because we've had a lot of issues with the public chat in the past (some community members getting locked out), we feel it'll be a better experience for our community and that discord is quite popular as a public chat platform in the wider crypto-space. Overall, we feel it’s a positive step towards helping our community grow.
While the chat link https://chat.golem.network will redirect to the Discord chat as of now, (https://discordapp.com/invite/y29dtcM)it will still be possible to post in the old Rocket chat for one week at https://old.chat.golem.network (EDIT: now depreciated). After one week, the public Rocket Chat will be put to Read-Only and archived. If you have any more questions or need help getting started with Discord, don’t hesitate to reach out.
