(I'm not that familiar with the situation and couldn't find any previous discussion of this, sorry if its already been covered. This email is cross posted to both the opentracing and grpc groups.)
Its confusing to users to have two copies of the code, so should be either (a) recognise the fork as the now "official" home, and at least add something to the README to direct users here or (b) perhaps invite the maintainer of the fork to the original repo so we can move it along, and close the fork?
Thanks
Tom
