Usernet requires at least one indexer and service provider. If you just got a provider your going to be missing a part of the tool chain. DM me if you need some help figuring what’s what.

Two ways come to mind.

One is tmux. The other is editing your .bashrc (I’m assuming your shell is bash, adjust accordingly if it’s a different shell) to have relevant info in your prompt (common is username@hostname).

Oh. also Windows Temrinal supports themes, and you can configure different commands to run when opening a given shell.

If memory holds, server admins can require any of (or none of) capchas, email verification, or manual approval for making a new account. They can also fully disable the ability to make accounts.
