SpecFlow OSS Ownership

I have been trying to get a Pull Request approved on the SpecFlow OSS project, but it looks like there's no longer any members of that project on GitHub. SpecFlowOSS/SpecFlow: #1 .NET BDD Framework. SpecFlow automates your testing & works with your existing code. Find Bugs before they happen. Behavior Driven Development helps developers, testers, and business representatives to get a better understanding of their collaboration (github.com)

What's going on with the OSS project? Does it have any maintainers or owners? Who should be working the Pull-Request process?
