So for some reason, I actually decided to read the main website at bzflag.org and found a few grammar errors in the text.
And I also think something could be improved by these sentences, but I don't know how to improve it or if it should be.Found a bug, a missing feature, or just something you thing should be improved?
Perhaps change to: "But you don't need to be a programmer to help out, you could work on..."You don't even necessarily have to be a programmer to help out. You could work on...
And on the Help page:
There are lots of ways to get help with BZFlag! Many of these are also useful if you want to help contribute to the game in some way.
Perhaps change to: "There are lots of ways to get help with BZFlag!; which can also be used to help contribute."
