Hi. Is it possible to combine users from a multisite so that a user can be registered on all multisites at the same time by registering on one of the sites (as in magento). Or a supervariant of using discourse, similar to federation. So that the alerts work synchronously and the user of site number 1 can receive alerts from site number 2? The same is true for the chat.
I have 4 communities of the same big direction, but different topics, and I would like these communities to be closely integrated with each other
