@pfefferle Done! Webfinger queries on emissary.dev and bandwagon.fm should now use the correct "template" argument. And I've updated the server-side lookups for #Emissary as well, so that they'll find the new (correct) value.
Here's a sample: https://emissary.dev/.well-known/webfinger?resource=acct%3Abenpate%40emissary.dev
Thanks Matthias!
