Here's a try, putting credits on the credits screen.
I would really hate to see something like that in the game. Especially with someone's name appearing four or five times.
A lot of people have contributed to WZ. Certainly, we owe a nod of thanks to Pumpkin for opening the source and making this project possible.
Since then, over time, there have been core groups of developers, but there are many people who have contributed in smaller but necessary ways: translators, patch submitters, people who take the time to file bug reports (hurray!), and the army of testers that make Open Source work. And let's not forget the people that keep our website and servers running.
Having a contributors page is a good idea, but unless it is scrollable, it is probably long enough that it should be a web page or text file included with the game. Paring it down to a minimal subset leaves too many people out; not good manners.
