When I started listing each page like that on the main page I didn't intend it to be a permanent thing, I just figured it was a good spot for a 'full index' sort of thing while we work out the overall format.
I think we should leave it as it is for the moment and move it to another page when the wiki goes public. Or we could just move it to another page now and replace it with a more compact index, but then we'd have to edit both indexes to make changes.
Also, once most pages are decided on, I can reformat the current main page so it splits into two columns, rather than one long list.
