We could easily create a template for each country's home page and you simply place that template on all the pages that are for that country specifically. The template could be a colored box showing a link to the country's home page. We need to decide if it is at the top of every page, or at the bottom.
At the top would be good because we can create a simple message telling the reader they are on a country specific page and give a link to the generic English guide. Then on all the generic English pages we can provide the link to the country specific editing table. If the other country managers wanted, we could even create an expandable (default closed) navbox
at the bottom of the page linking to the country specific versions of that page. The link from the top of the page could go to the bottom nav table for convenience. (I think we have the wiki extensions available to support the expand/contract settings, or could at least have the expanded table in the mean time.)
Something else we could do is create a navbox that highlights all the key editing, tips, etc., links. The template mentioned above would be the primary source and the info box would be for links to non-country specific information.
