@krisztianfekete I tried to add you to prometheus-client crates.io. Do you already have a crates.io account?

mxinden@mxinden-framework ~> cargo owner --add krisztianfekete prometheus-client
    Updating crates.io index
error: failed to invite owners to crate `prometheus-client` on registry at https://crates.io

Caused by:
  the remote server responded with an error (status 400 Bad Request): could not find user with login `krisztianfekete`

For others, I am bootstrapping trust off of #302.

Thanks! I think this should work: https://crates.io/users/krisztianfekete?

Great. Works now. Done.

mxinden@mxinden-framework ~ [101]> cargo owner --add krisztianfekete prometheus-client
    Updating crates.io index
       Owner user krisztianfekete has been invited to be an owner of crate prometheus-client

Thanks, @mxinden! One last blocker I have is that I cannot approve and merge my own PRs. I guess since we don't yet have other maintainers it might make sense to relax the requirements at least temporarily? cc. @brancz / @krajorama

[mxinden]

I assume you can add a pull request to the merge queue?

[krisztianfekete]

@mxinden, no I can only do that after an approve from someone else, see #306
