I make @surangak the owner of the FHIR module. Please go ahead and add whoever as maintainers.
For reference, I did this from the javascript console by making this REST call (which I can do as a modulus admin):
$.ajax({ method: "PUT", url: "https://modules.openmrs.org/modulus/api/modules/207", contentType: "application/json", data: JSON.stringify({"owner":"surangak"}) });
I first tried to add @dkayiwa as a maintainer via REST, like this
$.ajax({ method: "PUT", url: "https://modules.openmrs.org/modulus/api/modules/207", contentType: "application/json", data: JSON.stringify({"maintainers":[{"username":"harsha89"},{"username":"dkayiwa"}]}) });
…but this gave me a 500 response.
(Per this thread, we should really get the latest modulus+ui code running, so more of this stuff can be done via the UI.)
