I think it would a great idea to include a services thread where people can volunteer (or sell) their services to mod makers and the community. Programmers, graphic designers, voice actors, writers will have an easier time finding the right people to create mods together with and as a result your platform will have even more mods.
Or better mods.
In general, I think most people would be happy to volunteer some of their free time creating something together with other people. I most certainly would.
