To upload onto your ftp you must be using wanadoo access whether dial up or broadband. You cannot upload using another isp's access.
The hostname is sitebuilder.wanadoo.co.uk
The log in is
You then enter your password
You can have 5 sites
To start a site you must go through site builder ftp on the wanadoo site and define the site name. Your index page must be index.html and should be the first page you upload to the site.
You can enter the sitebuilder site and manually alter the coding which is very convenient as you need to enter file locations where it apears on the wanadoo server not your own hard drive.
You will have a steep learning curve but it is very rewarding.
All the information is on wanadoo site/members centre/build a website.
Good luck Pete
