Uploading your web is very dependent on your WEB HOSTING company.
Mine is TOTALCHOICEHOSTING
Go to FILE
PUBLISH WEB
You will need to type in your ftp address into the dialogue box as follows
ftp://76.35.296.141/public_html You can copy yours from the information your hosting company gave you.
(I changed the numbers above so it will go nowhere)
NOTE: I CLICK THE BUTTON THAT SAYS "PUBLISH CHANGED PAGES ONLY" that way as long as you use the same computer, it will only replace new pages you make or customize.
Push Publish and you will get prompted for a username and password
That's it!
