It has been pointed out several times already,
NO ONE HERE HAS ANY CONTROL OVER THE SCHOOL!!
I'm sure by now that the mod's are getting tired of telling you this and everyone else is getting tired of reading it.
If you want something added, changed or deleted on the school site, please contact them.
With a little research on your part, you would have found that you can contact them
directly with your concerns here ==> support@w3schools.com
Sorry if I seem a little short, but I've been trying to quit smoking and little things like this really get on my nerves!!!!
