We have defined a wiki template named "Default" and applied it to all existing wikis a while ago. Since then, I've found that all the new wikis being created select "-- New Template --" as their default and it must pull from some buried template in the source files (I assume) to generate a template that doesn't have any of the niceties we've added.
Is there a way to specify a default template to select for all new wikis that are created? This would make sure lazy admins don't accidentally goof up and forget to select "Default".
Our main motivation for a single template is to make pushing new features out to all wiki pages easy and low maintenance. If any wiki needs a unique style, that's fine, but those will be the exception and not the rule for us.
