OK,

one of the things that was mentioned at the big meeting was how it would be useful to see what people can help with.

Fortunately this is really easy to implement. If you go to your profile page / my account information (in right hand navigation), click Additional Info and you'll see a new box called "I can help with". In that box on each new line, write down things you can help others with, be it art, editing, game design, or whatever.
