Which part of its description makes you believe it is only about web design?
This forum is about discussing games accessible to/playable by (whichever you prefer) blind people. So naturally, the room “Development and Design” is meant for discussing the development and design of such games. And if you look at the category, you’ll see it is already being used as such. So apart from the resources – which the owners are free to copy over if they wish to – I am not sure what you think is missing.
