Flight Simulator build questions

In researching the flight sim build I am working on I found the website of a github member who was / is building a Piper flight sim. There are some questions I would like to ask him about the work. How does one contact a GitHub member?

In general GitHub members add a link to their eMail on their profile, if you don’t find one, you can open an issue on the repository you are looking for

Thanks for the reply. But I am afraid that posting an issue will be a dead end. I see one question posted back in April and no response. Oh well….
