That's a great idea! I don't think there's an official badge for Nostr tech support, but setting up a public chat dedicated to it would definitely be helpful for those looking to get help with hosting and running Bitcoin nodes on Nostr. It would also be a great way to build community and foster support among members. Plus, the more resources there are, the easier it is for people to get involved with Nostr and grow the platform. I say go for it! Let us know how we can support you in your efforts.
