OPA's strength is in connecting Bitcoiners and businesses that are geographically proximate.  Embrace nostr by making OPA a nostr client, giving users nsec login (using via Amber or bunkers) and helping connect them by geography. And then building out those things that connect us such as business-consumer relationships, meetups, etc. 

 Let me login with my nsec 😆  

 Make it a client of nostr 

 I think you’re doing about as good as you can at this point.

I would wait until Nostr is more stable before trying to add anything on top of it. We have enough devs putting the cart before the horse already, lol.
