Hi, it might be nice to have a subforum called “Constributions”, to post stuff one wants to contribute to Hedgewars.
Or it could be used to talk about features on which some people work. Or to give some sneak previews on the latest and greatest changes to HW, whatever.

There is already “Audio and Graphics” but this is only for art. Non-art contributions only really fit into the “General Discussion” forum. :/
So the contributions forum might be the place for custom missions, scripts, schemes, etc. all that stuff.
