Hello... my hosting site installed moodle and all looks good
http://mysite/moodle/all the files are here.
So how do I launch this to have a look see? I can't tell if I will like it untill I see something run in my browser
From your example URL, I wonder if you need to go to http://mysite/moodle, leaving off the "all." This is a common way that people install Moodle.
But maybe in your case, your hosting site actually has Moodle in that sample URL that you provide?
