WinFellow is maintained by a team of people; there is an overview over the current team of developers
here.
A lot of people have contributed something to it over the past, a more detailed list is in the latest build's documentation (the PDF that comes with the download has a credits chapter). It is hard to credit everyone fairly, and I hope we did not forget someone; many people have been involved with it in some form or the other over the years.
Thanks for your continued interest
