What you WP hackers should concentrate on as soon as possible is on converting the number of image directories in a multisite to just one.

There is the Google translator plugin of which the free version doesn’t take any SEO into account it seems, but there is also the paid version. How much do you think unless the owner is an entrepreneur can afford to spend on software? That WP is not really intended for professionals the web has been full of yet for years.
