I am on a costly slow and brief modem, mostly batched by wwwoffle. So it is hard for me to submit bugs and comments interactively.
Indeed there should be a page saying how 3rd world users could interact best with your site, e.g., It would be nice if there was a email way to add comments to discussion Talk: pages.
Also I would like to note that when one sees "Your account has been created. Don't forget to change your Wikipedia preferences.", the "Wikipedia preferences" should be a link!
