I will know by the end of the day if Nukes is right for my companies - product download site.
if you added an html page, you have to link to it in order for it to be accessed. ie: edit the "main" page and create a link to your new page.
right now the nukes 1.0 release only contains the "core" and the forums module. these have been deemed the most stable and ready for use.
work is currently under way to refactor and enhance the other modules you mentioned, but julien is the only full timer working on this and the rest of us contribute in our spare time, so at the moment, it's a rather slow going process (hey jboss ppl, i wanna work on nukes full time, can i have a job *smile*).
the wiki site does provide some documentation, but it is lacking in some areas and is being slowly updated as time goes on. if you discover answers to your questions on your own, feel free to add documention to the wiki site.
