``` ../../maufl/dtls/key_agreement.go:4:2: cannot find package "github.com/maufl/dhkx" in any of: /usr/local/Cellar/go/1.10.1/libexec/src/github.com/maufl/dhkx (from $GOROOT) /Users/nickysemenza/go/src/github.com/maufl/dhkx (from $GOPATH) ``` go get seems to indicate this might be a private repo?

similar fix as https://github.com/cloudflare/cfssl/pull/996/files#diff-bce1e9ac488e338e3aa3534151936e9f6e852a224ce9c9cb5e3f55529ca2fb76 is likely needed. Even better would be if they were ephemeral - generated during the tests.

shown here:  we should respond with a message saying you need to be more specific (first + last name) in the event that there are multiple matches

if user type `/karma` we should tell them to do `/karma [name]` (or tell them how to see the leaderboard when #93 is done)
