Well, there are actually a few things that can easily be done without any real computer knowledge. You could take a look at the
Create your own avatar in MS Paint topic, and by following those instructions it's surprisingly easy to make ok quality avatars. You could also just look at the site, and come up with any suggestions on how it could be better, or things that can be done. You could also go to the main site and see if you find any bug/errors that shouldn't be there. You could take a look at
the DKC History Month Project and maybe write up an article/editorial for that, or even just suggest ideas for articles that somebody else could write.
Remember, you don't even have to do anything to help. If you don't feel like doing anything, you can just suggest things that should be done. It's better than nothing.
