 Which configuration settings are safe enough for websetup?
 
+### Discussion pages
+
+Decide something, probably that "slave" pages, being only translations, don't
+deserve a discussion page: the discussion should happen in the language in which
+the pages are written for real, which is the "master" one.
+
+### parentlinks
+
+When the wiki home page is translatable, the parentlinks plugin sets
+`./index.html` as its translations' single parent link. Ideally, the home page's
+translations should get no parent link at all, just like the version written in
+the master language.
+
+### backlinks
+
+If a given translatable `sourcepage.mdwn` links to \[[destpage]],
+`sourcepage.LL.po` also link to \[[destpage]], and the latter has the master
+page *and* all its translations listed in the backlinks.
