Accounts are local to each instance. There is nothing stopping you from creating the user account, “dabu” at multiple instances, but there is little point in doing so. They are independent of each other, and currently, there is no concept of karma within the platform.

Your lemmy.world account can be used to post/reply on other instances (lemmy.ml, beehaw.org, etc.), and you can subscribe to communities on any other available instance so long as that particular instance is not blocked by your home instance.

I’ve primarily used Arch for my workstations since around 2007, and sometimes Debian Sid. I recently switched all of my workstations to Fedora Silverblue however, and I’ve been very happy with this type of workflow; flatpaks for user apps, containers for my dev environments, and automated image-based core OS updates. I am convinced this is the future of Linux computing for most users.

The use of ‘comm’ and ‘comms’ as short form for communities makes the most sense to me. Lemmy’s url path already uses /c/ as the designation as well.

Like ‘sub’ and ‘subs’, they are one syllable, and are easy to say and spell.

What kind of bandwidth and storage requirements might one expect with these user counts? I’m considering self-hosting an instance for migrating a couple of mostly text-based subs I work with (30-40K users).
