OH Ok, math problems, Love em.
So 60 seconds if your already logged into a site.
If your not and each site is at a different domain. 5 Minutes Per Customer Site, including Logging in testing and logging out.
At over 130 sites = 10.834 Hours spent
TOTAL WASTE OF MY TIME.
Not to mention that When you click on a Category, You get a 404 error? WTF..
