Congrats! Out of the usual suspects, (nginx, traefik & caddy), id say nginx has the steepest learning curve, so it’s definitely something to crow about mate! I know professionals in the tech industry that have a hard time with nginx config, so an enthusiast getting it down is a bigger deal than you’re giving yourself credit for.

I host various services for friends and family; and here are a couple I think will be of particular interest to you:

• matrix server with element clients. (Self hosted discord/WhatsApp alternative which is open source unlike TS).
• Drop server and client setup (self hosted steam like experience).

Another thing I would strongly suggest doing, is setting up a single sign on Auth server. Something that will allow your friends and family to have one login for anything you setup. Personally I use keycloak. But there are other options like authentik and voidauth that are worth looking at too!

Congrats again on the progress mate! You’re smashing it so far.
