I would, but do not see how it would be possible. It is a privately owned site, the owner of which has his own servers. You got servers lying around unused? Do you have any idea how much servers cost? Do you have skills to support such an endeavor.

From what?

Discord would be a good option. Easy to learn, similar features, and multiple users can be organizers/mods.

Though I like to come here several times a day to read and post, I would encourage folks to try Mastodon. Yes, it's different and you have to learn the interface. But, there is no obnoxious advertising to be forced to slide by. There are rules there that seem to be enforced. I was kicked off one instance, but joined another swiftly because it's a federation.

Admin owns the domain name and doesn't respond to inquiries so I don't see how this is possible.
