brew tap command doesn't work

[jacksonofalltrades]

Hi

I tried this:
brew tap thbishop/github-commit-status

And it prompts me for my github login. I enter it and my password and still get an error:
remote: Repository not found.
fatal: repository 'https://github.com/thbishop/homebrew-github-commit-status/' not found
Error: Failure while executing: git clone https://github.com/thbishop/homebrew-github-commit-status /usr/local/Library/Taps/thbishop/homebrew-github-commit-status --depth=1

Can you please provide guidance or update your doc to indicate that this command no longer works?

Thanks!
